STR6A161HVD - Sanken

STR6A161HVD Off-Line PWM Controller

The STR6A100xV/xVD series are power ICs for switching power supplies, incorporating a MOSFET and a current mode PWM controller IC. The operating mode of the IC automatically changes to green-mode or burst oscillation mode according to load in order to improve the all load efficiency. The product achieves high cost-performance power supply systems with few ex.
