STRW6251D PDF Datasheet – PWM Switching Regulator

This post explains for the Switching Regulator. A PWM (Pulse-Width Modulation) switching regulator, often referred to as a PWM DC-DC converter or simply a PWM regulator, is a type of electronic circuit used to efficiently convert one DC voltage to another, typically higher or lower, while maintaining a relatively constant output voltage. PWM switching regulators are widely used in various electronic devices and systems to provide stable and regulated power supplies with high efficiency.

The Part Number is STRW6251D, STRW6251.

The function of this semiconductor is PWM Switching Regulator.

Description

The STRW6251D series are current-mode PWM ICs that incorporate controller chips. These devices are manufactured using a proprietary high-voltage BCD process, and avalancheguaranteed MOSFETs. These elements allow power supply systems designs that are highly reliable and simple, with fewer
peripheral components. These ICs also provide Auto-Burst mode operation, which lowers input power requirements at light loads, and improves efficiency over the entire load range and universal-input range. […]

Features and Benefits :

1. Overcurrent protection (OCP) with ac input voltage compensation function; no additional peripheral circuits required-minimizes dependency of OCP on ac input

2. Overload protection (OLP) with integrated timer reduces power stress (temperature rise) at overload condition, requires no peripheral components

Applicatons include :

1. TV set top box

2. LCD PC monitor, LCD TV

3. Printer, scanner
