Test Points

VIN_EMI -

Input supply to EVM. Connect to a suitable input supply. See the

LM636x5-Q1 3.5-V to 36-

V, 1.5-A, and 2.5-A Automotive Step-down Voltage Converter Data Sheet

for input supply

requirements.

GND -

System power ground

VOUT -

Power output of EVM. Connect to desired load.

VOUTS -

Output voltage sense connection. Connect to DMM. It is also used for frequency response

analyzer connection (do not use for current; sense only).

VINS -

Input voltage sense connection. Connect to DMM (do not use for current; sense only).

GNDS -

Ground sense point for analog measurements. Connect to DMM (do not use for current; sense

only).

EN -

Connection for external EN logic input. Connect controlling logic to EN test point for external

enable control.

RESET -

Connected to the RESET pin of the IC. It is used as a flag output. The reset function can be

monitored at this test point. Pullup resistor, R

PULLUP

, must be populated. A typical value for pullup

resistor is 100 k

Ω

.

SYNC -

Connected to the SYNC pin of the IC. Connection to an external clock or synchronization

signal enables the IC switching frequency to follow the synchronization signal.

TPGND1, TPGND2 -
