BD9853AFV - Single/Dual-output High-frequency Step-down Switching Regulator

General Description

The BD9853AFV is a 2-ch synchronous DC/DC controller that can operate at a maximum switching frequency of 2MHz, enabling the use of a smaller external coil than conventional lower-frequency switching regulators.

This makes the BD9853AFV a suitable choice for downsizing applications.

Key Features

  • 1) Synchronous Switching Regulator Controller 2channels 2) FET(Pch/Nch) Direct Drive 3) Adjustable Oscillator Frequency with External Resistor (Max. 2MHz) 4) Under Voltage Lockout Function (UVLO) 5) Thermal Shut Down Function (TSD) 6) Short Circuit Protection (SCP) 7) Independent ON/OFF Function in Each Channel with Soft Start Pin 8) SSOP-B16 Package SSOPB16.
