FAN5307S18X Description

Short technical summary and product information.

The FAN5307S18X from ON Semiconductor is a high-efficiency, synchronous step-down DC-DC converter designed for battery-powered applications. It provides up to 300mA of output current from an input voltage range of 2.5V to 5.5V.

 

This device features a fixed 1MHz PWM operation and achieves up to 95% efficiency. It supports low dropout operation with a 100% duty cycle. In power-save mode, the quiescent current is reduced to 15µA, contributing to extended battery life.

 

The FAN5307S18X is available in a 5-lead SOT-23 package, suitable for surface mount applications. Its operating temperature range is -40°C to 85°C.

 

Key electrical characteristics include a 1.8V fixed output voltage, a 300mA maximum output current, and a 1MHz switching frequency. The input voltage range is 2.5V to 5.5V.
