FUNCTION

Supply voltage, usually direct from battery.

Regulated output 12V, 400mA (typ)

Ground connection.

CMOS compatible input pin; switches outputs on and off. When

ENABLE is high VOUT1 and VOUT2 are active.

Output 5V, 200mA (typ).

to VOUT1.

Kelvin connection that allows remote sensing of VOUT2 for

improved regulation. If remote sensing is not required, connect

to VOUT2.
