STRW6251D - PWM Switching Regulator

Download the STRW6251D datasheet PDF. This datasheet also covers the STR-W6251D variant, as both devices belong to the same pwm switching regulator family and are provided as variant models within a single manufacturer datasheet.

General Description

The STR-W6200D series are current-mode PWM ICs that incorporate controller chips.

These devices are manufactured using a proprietary high-voltage BCD process, and avalancheguaranteed MOSFETs.

Key Features

  • Overcurrent protection (OCP) with ac input voltage compensation function; no additional peripheral circuits required.
  • minimizes dependency of OCP on ac input.
  • Overload protection (OLP) with integrated timer reduces power stress (temperature rise) at overload condition, requires no peripheral components.
  • Avalanche-guaranteed MOSFET improves device capability of withstanding excess surge voltage, providing a simple surge absorber circuit without breakdown voltage derating.
