LT4430ES6#TRMPBF

The LT4430ES6#TRMPBF is a specialized power management IC designed to drive the opto-coupler in isolated power supplies. Manufactured by Analog Devices, this IC facilitates the crossing of the galvanic barrier, crucial for isolated power system designs.

Key electrical features include a wide input supply range of 3V to 20V and a high-bandwidth 9MHz error amplifier that simplifies frequency compensation. It provides a 10mA opto-coupler drive current with built-in current limiting and short-circuit protection. The device also incorporates a unique overshoot control function to prevent output overshoot during start-up and short-circuit recovery.

Packaged in a compact SOT-23-6 Thin package, the LT4430ES6#TRMPBF is suitable for surface mount applications. It operates across a temperature range of -40°C to 125°C, making it robust for various industrial and automotive environments. This component is ideal for applications such as isolated DC/DC converters, telecommunication power systems, and offline isolated power supplies.

This IC contains a precision-trimmed 600mV reference with ±0.75% initial accuracy and ±1.25% tolerance over temperature. Its ground-referenced opto-coupler drive ensures efficient operation within isolated power supply architectures.
