STR5A451D Datasheet (Sanken) - Off-Line PWM Controller

STR5A451D, Off-Line PWM Controller

The STR5A45xD Series is power ICs for switching power supplies, incorporating a MOSFET and a current mode PWM controller IC for non-isolated Buck converter and Inverting converter topologies.

The operation mode is automatically changed, in response to load, to the fixed switching frequency, to the s
