General Description
LT4430 General Description
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 amplifi er, 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 ±1.25% tolerance over temperature. A high bandwidth 9MHz error amplifi er permits simple frequency compensation and negligible phase shift at typical loop crossover frequencies. The optocoupler driver provides 10mA of output current and is short-circuit protected.
A unique overshoot control function prevents output overshoot on startup and short-circuit recovery with a
single capacitor.
The LT4430 is available in the low profi le 6-lead SOT-23 package.
