6.1 Demo Board Jumper Connections
JUMPER CONNECTION FUNCTION DESCRIPTION
Fail pin to +5V This jumper connects the FAIL pin to +5V thru a pull-ip resistor.
OVP - HW Controlled This jumper connects the OVP pin to a resistor divider which sets the
OVP value respect to the internal threshold of 6.9V. This resistor
divider is connected from Vout to GND. Please refer to Schematic to
set the correct resistance value based on your needs.
WAKE to GND This jumper connects the WAKE pin to GND.
WAKE operation This jumpers connects WAKE and PWM together, thus enabling the
low power consumption (shutdown) mode without the need of using
an extra logic signal for enable.
PWM pin to VDC1 Sets PWM pin to HIGH level, i.e. 100% duty cycle,
PWM pin to GND Sets PWM pin to LOW level, i.e. 0% duty cycle.
Chip enable Enables the IC as it takes EN to HIGH.
Chip disable DIsables the IC as it takes EN to GND. Connection used when
operating in WAKE operation.
LDO enable Powers up the +5V LDO regulator for the MCU and fail circuits.
MCU PWM signal Connects the the PWM signal generated by the MCU to the PWM pin
of the IC.
FAIL pin LED Connect LED for Fail condition indicator. When a fault situation is
detected such as an LED channel open or boost over-current this pin
goes into high impedance, making the LED to light up. (LED ON = Fail
Condition, LED OFF = OK)
Note: Jumpers J9 & J14 should not be connected at the same time.
6.2 Demo Board Operation
6.2.1 Stand Alone Mode, i.e. On-board PWM Dimming
Apply an external power supply to J1. When the LED D3 is turned on, it is possible to increase (SW1) or
decrease (SW2) the duty cycle of the PWM dimming signal generated by the MCU. When pressing both
switches at the same time and the LED D3 is turned off, it is possible to increase (SW1) up to 26.5KHz
or decrease (SW2) down to 200Hz the frequency of the PWM dimming signal generated by the MCU.
6.2.2 External Control Mode
Remove jumpers at J9 and J14. Apply an external power supply to J1. Thru a function generator apply a
0V to 5V square wave signal to the test point TP11. With this external signal, it is possible to evaluate the
PWM dimming performance of the MC34845 by varying both the frequency and duty cycle.

Jumper Function:
• Top horizontal jumpers: Channel strings enabled. This LED board has all channels populated but for
the KIT34845EPEVME it is only necessary to enable from I0 to I5.
• Bottom horizontal jumpers : Short circuits each of the current driver channels to the voltage of the
boost.
• Vertical jumpers: Enable/Disable 1,2,3,4 or 6 LEDs per string. Placing a jumper in the first vertical
header at the bottom will enable only 10 LEDs per string.

8.1 Network Compensation
Since this Boost converter is current controlled, a Type II compensation is needed. For this type of
compensation it is recommended to push out the Right Half Plane Zero to higher frequencies where it will
not significantly affect the overall

The crossover frequency must be set much lower than the location of the Right Half Plane Zero.

Since the MC34845 has a fixed slope compensation, RCOMP should be fixed for all configurations, i.e.
RCOMP = 8.2kΩ. As a result, CCOMP1 and CCOMP2 should be calculated as follows:

The recommended values of these capacitors for an acceptable performance of the system in different
operating conditions are CCOMP1 = C7 = 2.2nF and CCOMP2 = C8 = 56pF.
In order to improve the transient response of the boost a resistor divider, R2 and R10, has been
implemented from the PWM pin to ground with a connection to the compensation network. This
configuration injects a 1V signal to the COMP pin and the equivalent Thevenin resistance of the divider
is close to RCOMP, i.e. R2 = 10kΩ and R10 = 39kΩ.
If a faster transient response is needed, a higher voltage (e.g. 1.3V) should be injected to the COMP pin;
so the resistor divider should be modified accordingly but keeping the equivalent Thevenin resistance of
the divider close to RCOMP.

In some PWM dimming frequencies, it could be perceivable some audible noise from the input and output
capacitors of the boost converter. These micro-mechanical vibrations are an effect of the subharmonics produced
from the boost switching frequency.
In order to minimize this effect plus slightly improve the efficiency of the system, it is recommended to replace
