Description

The FR9885 is a synchronous step-down DC/DC converter that provides wide 4.5V to 18V input voltage range and 2A peak load current capability. At light load condition, the FR9885 can operate at PSM mode to support high efficiency and reduce power loss.

This is an electronic circuit used to efficiently reduce a higher input voltage to a lower output voltage. It is a type of switched-mode power supply (SMPS) that is commonly employed in a wide range of applications, including power management in electronics, battery chargers, voltage regulation, and more.

Features

1. Low Rds(on) Integrated Power MOSFET (170mΩ/135mΩ)

2. Internal Compensation Function

3. Wide Input Voltage Range: 4.5V to 18V

4. Adjustable Output Voltage Down to 0.6V

5. 2A Peak Output Current
