LT4430 Secondary-Side Optocoupler Driver www.datasheet4u.com ■ ■ ■ FEATURES 600mV Reference (1.25% Over Temperature) Wide Input Supply Range: 3V to 20V Overshoot Control Function Prevents Output Overshoot on Startup and Short-Circuit Recovery High Bandwidth Error Ampliﬁer Permits Simple Loop Frequency Compensation Ground-Referenced OptoCoupler Drive 10mA OptoCoupler Drive with Current Limiting Low Proﬁle (1mm) ThinSOTTM Package DESCRIPTIO ■ The LT®4430 drives the optocoupler that crosses the galvanic barrier in an isolated power supply. The IC contains a precision-trimmed reference, a high bandwidth error ampliﬁer, an inverting gain of 6 stage to drive the optocoupler and unique overshoot control circuitry. The LT4430’s 600mV reference provides ±0.75% initial accuracy and ±1.
