供应STR-W6252切换调整PWM(脉宽调制)电源IC

STR-W6252D

60 W-Universal Input/40 W-230 Vac Input
PWM Switching Regulators

Features and Benefits
▪ 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
▪ Start-up circuit eliminates the need for a start-up resistor,
and helps to reduce input power consumption

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. 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.
Applicatons include:
▪ TV set top box
▪ LCD PC monitor, LCD TV
▪ Printer, scanner
▪ General consumer, PC, and industrial applications
requiring SMPS power supply with standby mode
