Additional preview pages of the STR3A451 datasheet.

The STR3A400 series are power ICs for switching power supplies, incorporating a MOSFET and a current mode PWM controller IC.

Low Thermal Resistance Package.
Improving circuit efficiency (Since the step drive control can keep VRM of secondary rectification diodes low, the circuit efficiency can be improved by low VF).
Current Mode Type PWM Control.
Soft Start Function.
Automatic Standby Function No Load Power Consumption < 15mW.
Operation Mode Normal Operation -----------------------------PWM Mode Light Load Operation ------------------------ Green-Mode Standby ---------------------------.
