The LT4430ES6#TRPBF is an integrated circuit designed to drive the opto-coupler in isolated power supplies. It crosses the galvanic barrier, enabling isolated power delivery.
Key features include a precision-trimmed 600mV reference with ±0.75% initial accuracy and ±1.25% tolerance over temperature. The device operates with a wide input supply range of 3V to 20V. It incorporates a high bandwidth 9MHz error amplifier, which simplifies frequency compensation and minimizes phase shift. The opto-coupler driver provides 10mA of output current and includes short-circuit protection.
A unique overshoot control function is integrated to prevent output overshoot during start-up and short-circuit recovery, requiring only a single capacitor. This IC is suitable for applications such as 48V input isolated DC/DC converters, isolated telecommunication power systems, distributed power step-down converters, offline isolated power supplies, industrial control systems, and automotive/heavy equipment power supplies.
The LT4430ES6#TRPBF is supplied in a low profile 6-lead TSOT-23 package, designed for surface mounting.
