Test Points

VIN -

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

LMR33630 data sheet

for input

supply requirements.

GND -

System power ground

VOUT -

Power output of EVM. Connect to desired load.

VOS -

Output voltage sense connection; connect to DMM. Also, used for frequency response analyzer

connection.

VIS -

Input voltage sense connection; connect to DMM.

GNDS -

Ground sense point for analog measurements; connect to DMM.

VCC -

Test point to measure internal VCC of device; approximately 5 V. On-board PGOOD pullup

resistor is connected to VCC.

EN -

Connection for external EN logic input. Remove EN jumper and connect controlling logic to EN

test point for external enable control.

PGOOD -

Power good flag output. This test point is connected to VCC through a 20-k

Ω

resistor. The

power-good function can be monitored at this test point.

A -

Connection for frequency response analyzer (on bottom of board) - see

Figure 5
