PIN FUNCTION DESCRIPTION

Pin
Symbol
Description
15
OUT1
Main output of the PWM Controller. OUT1 has a source resistance of 4.0 (typ.) and a sink resistance
of 2.5 (typ.). OUT1 is designed to handle up to 2.5 A. OUT1 trails OUT2 during a low to high
transition and leads OUT2 during a high to low transition.

V
AUX
Positive input supply. This pin connects to an external capacitor for energy storage. An internal current
source supplies current from V
in
to this pin. Once the voltage on V
AUX
reaches approximately 10.3 V,
the current source turns OFF and the outputs are enabled. It turns ON again once V
AUX
falls to 8.0 V. If
the bias current consumption exceeds the startup current, V
AUX
will continue to discharge. Once V
AUX
reaches 7.0 V, the outputs are disabled allowing V
AUX
to charge. During normal operation, power is
supplied to the IC via this pin by means of an auxiliary winding. The startup circuit is disabled once the
voltage on the V
AUX
pin exceeds 10.3 V. If the V
AUX
voltage drops below 1.2 V (typ), the startup
current is reduced to 200 A.
