STR-W6251D 30 W-Universal Input/45 W-230 Vac Input PWM Switching Regulators

STR-W6251D Description

STR-W6251D 30 W-Universal Input/45 W-230 Vac Input PWM Switching Regulators .
The STR-W6200D series are current-mode PWM ICs that incorporate controller chips.

STR-W6251D 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

STR-W6251D Applications

* requiring SMPS power supply with standby mode Package: TO-220 Not to scale Functional Block Diagram VCC 7.1 V STARTUP UVLO 15.5 V/ 8.9 V 7.1 V D/ST REG VREG 28.5 V OVP ELP TSD RST R SQ =1.6 mA I startup DMAX 75% RQ S DRV PWM OSC SQ R S2 Q FM/ELP Frequency Modulation 12 V 7.8 V O
