CONTROL SIGNALS

Status

Description

Power Good (PG) indication

This signal is used to detect the presence of output voltage. This signal goes high when input power is applied and output voltage is more

than 85% of nominal 12.0 VDC output. Signal type: TTL-compatible, with 2.43K pull-up resistor to +5V.

Enable

Active low input to enable +12VDC output of power supply.

+Sense

Positive side of Remote Sense input.

-Sense

Negative side of Remote Sense input.

5V AUX

+5V standby.

Current Share

Single-wire current-share connection.

LED Drive

10mA min. When PG is high, Pin 1 of J2 shall go high to illuminate external GREEN LED. When PG is low, Pin 3 of J2 shall go high to

illuminate external YELLOW LED.
