STR-A6159 - Off-Line PRC Controllers

General Description

The STR-A6100 series are power ICs for switching power supplies, incorporating a MOSFET and a current mode PRC controller IC.

PRC (Pulse Ratio Control) controls on-time with fixed off-time.

The IC includes a startup circuit and a standby function to achieve the low standby power.

Key Features
