Symbol
OUT1
V
AUX
Main output of the PWM Controller. OUT1 has a source resistance of 4.0 Ω (typ.) and a sink resistance
of 2.5 Ω (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.
Positive input supply. This pin connects to an external capacitor for energy storage. An internal current
source supplies current from V
the current source turns OFF and the outputs are enabled. It turns ON again once V
the bias current consumption exceeds the startup current, V
reaches 7.0 V, the outputs are disabled allowing V
supplied to the IC via this pin by means of an auxiliary winding. The startup circuit is disabled once the
voltage on the V
