Secondary-Side
Optocoupler Driver
The LT
4430 drives the optocoupler that crosses the
galvanic barrier in an isolated power supply. The IC con-
tains 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 ±1.25% tolerance over temperature. A high
bandwidth 9MHz error amplifier 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 profile 6-lead SOT-23
package.
