STRW6000S - PWM Off-Line Switching Regulator

This page provides the datasheet information for the STRW6000S, a member of the STR-W6000S PWM Off-Line Switching Regulator family.

Description

The STR-W6051S, STR-W6052S, and STR-W6053S are power ICs for switching power supplies, incorporating a power MOSFET and a current mode PWM controller IC in one package.

To achieve low power consumption, these products include a startup circuit and a standby function in the controller.

Features

  • Current mode PWM control.
  • Brown-In and Brown-Out function: auto-restart, prevents excess input current and heat rise at low input voltage.
  • Auto Standby function: improves efficiency by Burst mode operation in light load ▫ Normal load operation: PWM mode ▫ Light load operation: Burst mode.
  • No load power consumption < 30 mW.
  • Operating frequency, fOSC(AVG)(typ) = 67 kHz.
  • Random Switching function: reduces EMI noise, and simplifies EMI filters.
  • Slope Compensation.
