Setup and Test Results

3.1.3

J3 – GND

This header is the return connection for the input power supply used for lower (< 1A) input currents.

3.1.4

J4 – GND

This header is the return connection for the load and/or output multimeter used for lower (< 1A) output
currents.

3.1.5

J5 pin 1 – SYNC

This pin is available for the application of an external clock synchronization signal. Make sure that the
frequency of the clock signal is within the range in

Table 1

. This pin cannot be left floating, so use a

shorting jumper to short the SYNC pin to GND if not used.

3.1.6

J5 pin 2 – GND

This pin is the return connection for the external synchronization signal

3.1.7

J6 pin 1 – V

This is the positive connection for the input power supply used for higher (> 1A) input currents.

3.1.8

J6 pin 2 – GND

This is the return connection to the input power supply used for higher (> 1A) input currents. Twist the
leads to the input supple, and keep them as short as possible.

3.1.9

J7 pin 1 – GND

This is the return connection for the load used for higher (> 1A) output currents.

3.1.10

J7 pin 2 – V

OUT

This is the positive connection for the load used for higher (> 1A) output currents.

3.1.11

JP1 – ENABLE

Installing this jumper ties the enable pin to either the input voltage (on) or ground (off). If left unconnected,
the enable pin’s internal pull down resistor disables the IC.

3.1.12

TP1 – SW Node

Test point for the switch node of the boost converter.

3.1.13

TP2 – Loop Response

Test point for control loop response measurements.

3.1.14

TP3 – Comp Pin

Test point for the compensation network.

3.1.15

TP4 and TP5 – Output Ripple

Test points for measuring the output ripple voltage.

3.1.16

TP6 – V

Test point for measuring the input voltage.
