STR-A6061MZ - Sanken

STR-A6061MZ Off-Line PWM Controllers

The STR-A6000MZ/HZ series are power ICs for switching power supplies, incorporating a power MOSFET and a current mode PWM controller IC. The low standby power is accomplished by the automatic switching between the PWM operation in normal operation and the burst-oscillation under light load conditions. The product achieves high costperformance power supply sy.
