Interface Signals

PFD

TTL logic high for normal operation and TTL logic low upon loss of input power.

This signal appears at least 1ms prior to V1 output dropping 5% below its nomi-

nal value. This signal also provides a minimum delay of 100 ms after V1 is with-

in regulation.

Inhibit

Requires an external TTL high level signal to inhibit outputs for standard mod-
