Pin Configuration (top view)
Pin Definitions and Functions
GROUND; all four pins connected to the heat sink
Enable 1; Enable for Main Output Q1 and Q2; E1, E2 and E3 are
ored together; connect to GND, if not needed.
Input; block to ground directly at the IC for line compensation.
Tracking Output Q2; block to GND with min. 10 F with
ESR < 3 .
Reference Output; Reference Voltage related to Q2.
Reset Output; the open collector Output is connected to Q1 via an
integrated resistor.
Reset Delay; connect a capacitor to GND for reset delay time
adjustment.
Enable 2; Enable for Main Output Q1 and Q2; E1, E2 and E3 are
ored together; connect to GND, if not needed.
Main Output Q1; block to GND with min. 22 F, ESR < 3 .
Reset Switching Threshold Adjust; The reset threshold can be
set individually with an external voltage divider at the pin. If it is
connected straight to GND the reset threshold remains at 4.65 V.
