3 Description
The LM2765 CMOS charge-pump voltage converter
operates as a voltage doubler for an input voltage in
the range of 1.8 V to 5.5 V. Two low-cost capacitors
and a diode are used in this circuit to provide up to 20
mA of output current.
The LM2765 operates at 50-kHz switching frequency
to reduce output resistance and voltage ripple. With
an operating current of only 130 µA (operating
efficiency greater than 90% with most loads) and 0.1-
µA typical shutdown current, the LM2765 provides
ideal performance for battery powered systems. The
device is manufactured in a 6-pin SOT-23 package.

8 Detailed Description
8.1 Overview
The LM2765 CMOS charge-pump voltage converter operates as a voltage doubler for an input voltage in the
range of 1.8 V to 5.5 V. Two low-cost capacitors and a diode (needed during start-up) are used in this circuit to
provide up to 20 mA of output current.
8.2 Functional Block Diagram
8.3 Feature Description
8.3.1 Circuit Description
The LM2765 contains four large CMOS switches which are switched in a sequence to double the input supply
voltage. Energy transfer and storage are provided by external capacitors. Figure 9 shows the voltage conversion
scheme. When S2and S4are closed, C1charges to the supply voltage V+. During this time interval, switches S1
and S3are open. In the next time interval, S2and S4are open; at the same time, S1and S3are closed, the sum
of the input voltage V+ and the voltage across C1gives the 2 V+ output voltage when there is no load. The
output voltage drop when a load is added is determined by the parasitic resistance (Rds(on) of the MOSFET
switches and the ESR of the capacitors) and the charge transfer loss between capacitors. See Application and
Implementation for more details.
Figure 9. Voltage Doubling Principle
8.4 Device Functional Modes
8.4.1 Shutdown Mode
A shutdown (SD) pin is available to disable the device and reduce the quiescent current to 1 µA. In normal
operating mode, the SD pin is connected to ground. The device can be brought into the shutdown mode by
applying to the SD pin a voltage greater than 40% of the V+ pin voltage.

9 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers must
validate and test their design implementation to confirm system functionality.
9.1 Application Information
The LM2765 provides a simple and efficient means of creating an output voltage level equal to twice that of the
input voltage. Without the need of an inductor, the application solution size can be reduced versus the magnetic
DC-DC converter solution.
9.2 Typical Applications
9.2.1 Voltage Doubler
The main application of the LM2765 is to double the input voltage. The range of the input supply voltage is 1.8 V
to 5.5 V.

9.2.1.2 Detailed Design Requirements
9.2.1.2.1 Positive Voltage Doubler
The output characteristics of this circuit can be approximated by an ideal voltage source in series with a
resistance. The voltage source equals 2 V+. The output resistance ROUT is a function of the ON resistance of the
internal MOSFET switches, the oscillator frequency, the capacitance and equivalent series resistance (ESR) of
C1and C2. Since the switching current charging and discharging C1is approximately twice as the output current,
the effect of the ESR of the pumping capacitor C1will be multiplied by four in the output resistance. The output
capacitor C2is charging and discharging at a current approximately equal to the output current, therefore, its
ESR only counts when in the output resistance. A good approximation of ROUT is:
where
RSW is the sum of the ON resistance of the internal MOSFET switches shown in Figure 9. RSW is typically 8 Ω
for the LM2765. (1)
The peak-to-peak output voltage ripple is determined by the oscillator frequency, the capacitance and ESR of the
output capacitor C2:
(2)
High capacitance, low-ESR capacitors can reduce both the output resistance and the voltage ripple.
The Schottky diode D1is only needed for start-up. The internal oscillator circuit uses the OUT pin and the GND
pin. Voltage across OUT and GND must be larger than 1.8 V to insure the operation of the oscillator. During
start-up, D1is used to charge up the voltage at the OUT pin to start the oscillator; also, it protects the device from
turning-on its own parasitic diode and potentially latching-up. Therefore, the Schottky diode D1must have
enough current carrying capability to charge the output capacitor at start-up, as well as a low forward voltage to
prevent the internal parasitic diode from turning-on. A Schottky diode such as 1N5817 can be used for most
applications. If the input voltage ramp is less than 10 V/ms, a smaller Schottky diode such as MBR0520LT1 can
be used to reduce the circuit size.
9.2.1.2.2 Capacitor Selection
As discussed in Positive Voltage Doubler, the output resistance and ripple voltage are dependent on the
capacitance and ESR values of the external capacitors. The output voltage drop is the load current times the
output resistance, and the power efficiency is:
where
IQ(V+) is the quiescent power loss of the device; and
IL2Rout is the conversion loss associated with the switch on-resistance, the two external capacitors and their
ESRs. (3)
The selection of capacitors is based on the specifications of the dropout voltage (which equals IOUT ROUT), the
output voltage ripple, and the converter efficiency. Low ESR capacitors are recommended to maximize efficiency,
reduce the output voltage drop and voltage ripple.
9.2.1.2.3 Paralleling Devices
Any number of LM2765 devices can be paralleled to reduce the output resistance. Each device must have its
own pumping capacitor C1, while only one output capacitor, COUT, is required as shown in Figure 11. The
composite output resistance is:
ROUT = ROUT of each LM2765 / number of devices (4)

Figure 11. Lowering Output Resistance by Paralleling Devices
9.2.1.2.4 Cascading Devices
Cascading the LM2765 devices is an easy way to produce a greater voltage (a two-stage cascade circuit is
shown in Figure 12).
The effective output resistance is equal to the weighted sum of each individual device, shown in Equation 5:
ROUT = 1.5 ROUT_1 + ROUT_2 (5)
Note that the increasing of the number of cascading stages is practically limited since it significantly reduces the
efficiency, increases the output resistance and output voltage ripple.
Figure 12. Increasing Output Voltage by Cascading Devices
9.2.1.2.5 Regulating VOUT
It is possible to regulate the output of the LM2765 by use of a low dropout regulator (such as LP2980-5.0). The
whole converter is depicted in Figure 13.
A different output voltage is possible by use of LP2980-3.3, LP2980-3.0, or LP2980-ADJ.
Note that the following conditions must be satisfied simultaneously for worst-case design:
2Vin_min > Vout_min + Vdrop_max (LP2980) + Iout_max × Rout_max (LM2765) (6)
2Vin_max < Vout_max + Vdrop_min (LP2980) + Iout_min × Rout_min (LM2765) (7)

10 Power Supply Recommendations
The LM2765 is designed to operate from as an inverter over an input voltage supply range between 1.8 V and
5.5 V. This input supply must be well regulated and capable to supply the required input current. If the input
supply is located far from the device, additional bulk capacitance may be required in addition to the ceramic
bypass capacitors.

11 Layout
11.1 Layout Guidelines
The high switching frequency and large switching currents of the LM2765 make the choice of layout important.
Use the following steps as a reference to ensure the device is stable and maintains proper LED current
regulation across its intended operating voltage and current range.
Place CIN on the top layer (same layer as the LM2765) and as close as possible to the device. Connecting
the input capacitor through short, wide traces to both the V+ and GND pins reduces the inductive voltage
spikes that occur during switching which can corrupt the V+ line.
Place COUT on the top layer (same layer as the LM2765) and as close as possible to the OUT and GND pin.
The returns for both CIN and COUT must come together at one point, as close as possible to the GND pin.
Connecting COUT through short, wide traces reduce the series inductance on the OUT and GND pins that can
corrupt the VOUT and GND lines and cause excessive noise in the device and surrounding circuitry.
Place C1 on the top layer (same layer as the LM2765 device) and as close as possible to the device.
Connect the flying capacitor through short, wide traces to both the CAP+ and CAP– pins.
