Description PeakSwitch is designed to address applications with high peakto-continuous power ratio demands. The very high switching frequency during peak power loads and excellent load transient response reduce system cost as well as component count and size. PeakSwitch incorporates a 700 V power MOSFET, oscillator, high voltage switched current source for startup, current limit, and thermal shutdown onto a monolithic device. In addition, these devices incorporate auto-restart, line under-voltage sense and frequency jittering. An innovative design minimizes audio frequency components in the simple ON/OFF control scheme to practically eliminate audible noise with standard varnished transformer construction.

Pin Functional Description Y Package (TO-220-7C) Tab Internally Connected to SOURCE Pin 7D 5 NC 4S 3 EN/UV 2 GND 1 BP DRAIN (D) Pin: The power MOSFET drain connection provides internal operating current for both startup and steady-state operation. BYPASS (BP) Pin: A 0.33 µF external bypass capacitor for the internally generated 5.8 V supply is connected to this pin. In typical applications, this pin must be externally supplied via a bias winding. ENABLE/UNDER-VOLTAGE (EN/UV) Pin: This pin has dual functions: enable input and line under-voltage sense. During normal operation, switching of the power MOSFET is controlled by this pin. MOSFET switching is disabled when a current greater than 240 µA is drawn from this pin. This pin may also sense line under-voltage conditions through either an external resistor connected to the DC line voltage or an AC sense circuit. SOURCE (S) Pin: This is the MOSFET source connection for high voltage return and control circuit common.
