Description
STR-W6252D www.DataSheet4U.com 60 W-Universal Input/40 W-230 Vac Input PWM Switching Regulators .
The STR-W6200D series are current-mode PWM ICs that incorporate controller chips.
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 peripher
Applications
* requiring SMPS power supply with standby mode
Package: TO-220
