FAN2103 is a 3A synchronous buck regulator from Fairchild Semiconductor. It has an output current of 3A, efficiency of 95% or more, support for external compensation, programmable switching frequency, low input voltage lockout, programmable over-current limit and other features.
The FAN2103 is an easy-to-use, cost- and space-efficient 3A synchronous buck solution designed for high current requirements in small areas. It features fully synchronous operation with an integrated Schottky diode on the low-side MOSFET to boost efficiency.
Key design features include programmable switching frequency (200kHz to 600kHz), external compensation, and a power-good signal. The device accepts ceramic capacitors on the output and includes comprehensive protections such as under-voltage lockout, over-current limit, and thermal shutdown.
