STR3A461HL - Off-Line PWM Controller

This page provides the datasheet information for the STR3A461HL, a member of the STR3A461HDL Off-Line PWM Controller family.

Datasheet Summary

Description

The STR3A46xHL/HDL series are power ICs for switching power supplies, incorporating a power MOSFET and a current mode PWM controller IC.

To enhance efficiency in all load ranges, the IC automatically shifts its operation to the green mode or burst oscillation mode, depending on the load.

Features

  • Bare Lead Frame: Pb-free (RoHS compliant).
  • 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).
  • Noise Reduction.
  • 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---.
