The APW7095/A is a 6-channel, frequency-settable,
voltage-mode, DC/DC control IC providing a complete
power supply solution for high-performance portable
digital cameras. The APW7095/A uses pulse-width-
modulation (PWM) and synchronous rectification for
high efficiency step-up, step-down, up-down and in-
verting converters with free input and output settings
in 2 or 4-cell AA, 1-cell lithium-ion (Li+), and dual-
battery designs. The APW7095/A incorporates error
amplifiers, output short-circuit detection, under-volt-
age lockout, soft-start and output switch control into
a chip. The AP7095/A improves performance, compo-
nent count, and size compared to conventional multi-
channel controllers.
The APW7095/A has a power-good indicator (PGOOD)
that signals when CH1 output is within ±10% of the
set voltage by monitoring IN1 pin.
The APW7095/A is available in compact 48-pin plas-
tic LQFP and TQFN packages.

Function Descriptions
General
The APW7095/A provides voltage-mode feedback con-
trols for six DC/DC PWM converters(CH1 to CH6).
Each channel operates with an error amplifier, PWM
comparator, short-circuit comparator, ON/OFF con-
trol and output driver. An internal temperature-com-
pensated voltage provides reference voltages for each
channel. An triangular-wave oscillator(CT) with a tim-
ing resistor and capacitor generates triangular waves
to each channel. A inverting amplifier(CH4) cooper-
ates with the error amplifier for an inverting converter
(with negative output voltage) .
Reference Voltage
The APW7095 outputs a temperature- compensated
reference voltage(2.49V) at VREF pin. It is regulated
from the voltage at VCC pin and can source current of
max. 1mA to external loads. It also supplies bias for
the IC’s internal circuitry.
Triangular-wave Oscillator
The triangular-wave oscillator is designed to gener-
ates a triangular oscillation signal (CT) with amplitude
of 0.3V~0.8V at CT pin, providing signal to CH6. The
oscillator frequency is settable from 100kHz to 1MHz
and set by a timing resistor and a timing capacitor
connected respectively from RT and CT pins to ground.
Additional two triangular oscillation signals (CT1 and
CT2) are also internally generated with amplitude of 1.
1V~1.8V. The CT1 is in phase with the CT to the PWM
comparators of CH2 and CH4; the CT2 is out of phase
with the CT to the PWM comparators of CH1, CH3
and CH5.
Error Amplifier
The error amplifier is designed with unit-gain-bandwidth
of 1MHz and to satisfy wide application requirements.
It works with enternal resistor-capacitor network for
each converter’s feedback compensation. The loop gain
can be set by connecting a feedback resistor and
capacitor from the output pin(FB) to inverted input pin
of the error amplifier for stable operations.
Inverting Amplifier (Inv Amp)
The inverting amplifier detects the inverting DC/DC con-
verter output voltage (as a negative voltage) and out-
puts a control signal to the error amp.
Channel Control Function
The channel control function turns on/off one or more
channels depending on the states (“H” or “L” level) at
CTL, CTL1,2 to CTL5 pins. The on/off control logic is
shown as the following table:

Function Descriptions (Cont.)
Timer-latch short-circuit protection circuit
The short-circuit protection comparator in each chan-
nel (CH1 to CH5) monitors converter’s output voltage
via input pin of error amplifier. In CH6, the short-circuit
comparator detects the voltage at output of error
amplifier. As any detected voltages of CH1 to CH5
falls below 1.0V or the detected voltage of CH6 is larger
than 0.9V, the timer circuits is actuated to start charg-
ing the external capacitor CSCP connected from CSCP
pin to ground. When the rising voltage of CSCP reaches
0.7V, the IC turns off all external MOSFETs and pulls
up the voltage at SWOUT pin. Then the IC is latched.
Applying a signal from “L” to “H” to CTL pin enables
operation again. The short-circuit detection function
remains working during soft start operation on CH1 to
CH5.
Under-Voltage Lockout (UVLO) Circuit
The under-voltage lockout circuit monitors the supply
voltage at VCC pin to prevent wrong logic control. The
IC starts operation after the supply voltage rises above
it’s rising threshold. As the supply voltage falls below
it’s falling threshold, the IC turns off the external
MOSFETs and pulls up the voltage at SWOUT pin.
Soft-Start Operation
The soft-start function controls the output voltage rate
of rise to limit the current surge at start-up. For CH1
to CH5, the soft-start interval is programmed by the
soft-start capacitor, CS connected from CS pin to
ground and charged by an internal 1µA current source.
For CH6, a soucing current from the internal resistor-
divider charges the capacitor, CCIN6 connected from
CIN6 pin to ground, providing soft-start control.
Figure 1 and 2 show the soft-start processes. In figure
1, when all control pins (CTL, CTL1,2 to CTL 5) are
driven high (“H” level) at the same time, the voltage at
CIN6 pin starts to rise up by charging the capacitor
CCIN6 , starting a soft-start operation on CH6. After the
rising voltage at CIN6 reaches 0.9V, the reference volt-
age starts to regulate and the internal source current
starts to charge the CS , starting a soft-start operation
on CH1 to CH5. During soft-start interval, the error
amplifiers compares the CH1 to CH5 output voltage to
the voltage at the CS pin. When any control pins (CH1,
2 to CH5) go “H” from “L” during the soft-start interval
(CH1 to CH5), the output rises rapidly to follow the
rising voltage at CS pin.

Output Switch Control Circuit
The output switch control circuit outputs a signal to
control external p-channel MOSFETs for preventing
reactive current flow to external step-up circuits on
CH5 and CH6. When a “H” level
signal is applied to SWIN pin after releasing the UVLO
and the voltage at CIN6 pin rises above 0.9V(typical),
the IC pulls low the voltage at SWOUT pin, turning on
the external p-channel MOSFETs to generate output
voltages.

Dead-Time Setting
The dead-time control pin (DTC) is designed to set
the maximum ON duty of the main-side MOSFET.
When the device is set for step-up inverted output based
on the step-up or step-up/down Zeta method or flyback
method, the FB pin voltage may reach and exceed
the triangular wave voltage due to load fluctuation. If
this is the case, the output MOSFET is fixed to a ON
duty of 100 %. To prevent this, set the maximum duty
of the output MOSFET. Connecting a resistor- divider
between VREF, DTC and GND pins provides a volt-
age VDTC to DTC pin. When the the voltage at the
DTC pin is higher than the triangular wave voltage (CT1/
2), the output transistor is turned on. The maximum
duty is calculated as the following equation:

where VREF is the output of the reference voltage (2.
