LT4430  
Secondary-Side  
Opto-Coupler Driver  
FEATURES  
DESCRIPTION  
The LT®4430 drives the opto-coupler that crosses the gal-  
vanic 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 opto-  
coupler and unique overshoot control circuitry.

High Bandwidth Error Amplifier Permits Simple Loop  
Frequency Compensation  
Ground-Referenced Opto-Coupler Drive  
The LT4430’s 600mV reference provides ±0.ꢀ75 initial  
accuracy and ±±.ꢁ75 tolerance over temperature. A high  
bandwidth9MHzerroramplifierpermitssimplefrequency  
compensation and negligible phase shift at typical loop  
crossover frequencies. The opto-coupler driver provides  
±0mA of output current and is short-circuit protected.  
A unique overshoot control function prevents output  
overshoot on start-up and short-circuit recovery with a  
single capacitor.
