STR4A162D

Package Image

Package:DIP8 (Pin 3 Removed)

The STR4A100 series are power ICs for switching power supplies, incorporating a sense 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 cost-performance power supply systems with few external components.
