General Description

The BL9309 is a high-efficiency, DC-to-DC step-down switching regulators, capable of delivering up to 2A of output current.

The device operates from an input voltage range of 2.5V to 5.5V and provides an output voltage from 0.6V to VIN, making the BL9309 ideal for low voltage power conversions.

Running at a fixed frequency of 1.3MHz allows the use of small external ponents, such as ceramic input and output caps, as well as small inductors, while still providing low output ripples.

Key Features

  • High Efficiency: Up to 97%.
  • Capable of Delivering 2A.
  • 1.3MHz Switching Frequency.
  • No External Schottky Diode Needed.
  • Light-load Mode.
  • Internal Compensation and Soft-Start.
  • Current Mode control.
  • 0.6V Reference for Low Output voltages.
  • Logic Control Shutdown (IQ.
