The FAN5099 is a wide frequency synchronous buck PWM and LDO controller, with high efficiency, low power consumption and multiple applications
The FAN5099 combines a high‑efficiency pulse‑width‑modulated (PWM) controller with a low‑drop‑out (LDO) linear regulator. It operates over a wide input voltage range (3 V‑24 V) and supports a programmable switching frequency from 50 kHz to 600 kHz, making it suitable for high‑efficiency DC‑DC converters, computer power supplies, and FPGA/DSP applications.
The device is offered in industrial (‑40 °C to +85 °C) and commercial (‑10 °C to +85 °C) temperature grades and is available in 16‑lead TSSOP and SOIC packages. Detailed electrical characteristics, absolute maximum ratings, and typical performance graphs are provided for design reference.
