STRW6251, STR-W6251D PWM Switching Regulator

STRW6251 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.

STRW6251 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

STRW6251 Applications

* requiring SMPS power supply with standby mode Not to scale Functional Block Diagram VCC UVLO 15.5 V/ 8.9 V REG VREG PWM OSC DMAX 75% SQ R 28.5 V OVP 7.1 V ELP TSD 7.1 V RST R SQ RQ S STARTUP Istartup =1.6 mA DRV FM/ELP 12 V FB Frequency Modulation 7.8 V 160 μA S2 Q OLP CK tOLP = S1
