Bench Test Setup Conditions

Headers Description and Placement

Please carefully inspect the EVB IC and external components, comparing them to the following Bill of Materials, to ensure that all components are

installed and undamaged. If any components are missing or damaged during transportation, please contact the distributor or send e-mail to

Test Points

The EVB is provided with the test points and pin names listed in the table below.

Test point/

Pin name

Signal

Comment (expected waveforms or voltage levels on test points)

VIN

Input voltage

Input voltage range= 4.5V to 36V

VOUT

Output voltage

Default output voltage = 5.0V

Output voltage range= 0.8V to 15V

(see „‟ Output Voltage Setting‟‟ section for changing output voltage level)

SW

Switching node test point

SW waveform

EN

Enable test point

Enable signal. EN is automatically pulled high by internal circuit to enable

operation. Connect EN low (or by R4 pull low resistor) to disable operation.

BST

Boot strap supply test point

Floating supply voltage for the high-side N-MOSFET switch

GND

Ground

Ground

Power-up & Measurement Procedure

1.

2.

The EN voltage is pulled to logic high by internal circuit to enable operation. Drive EN high (>2.5V) to enable

operation or low (<0.4V) to disable operation.

3.

There is a 3-pin header JP2

“EN” for enable control. To use a jumper at “H” option to tie EN test pin to input

power VIN for enabling the device. Inversely, to use a jumper at

“L” option to tie EN test pin and ground GND

for disabling the device.
