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
