TECHNICAL NOTE

Single-chip built-in FET type Switching Regulator Series

Simple Step-down

Switching Regulator

with Integrated Compensation

BD9322EFJ, BD9323EFJ, BD9324EFJ

zDescription

The BD9322EFJ, BD9323EFJ and BD9324EFJ are step-down regulators that integrate a low resistance high side N-channel

MOSFET.

It achieves 2A / 3A / 4A continuous output current over a wide input supply range.

Current mode operation provides fast transient response and easy phase compensation.

zFeatures

1) Wide operating INPUT Range 4.75V～18V

2) Selectable 2A / 3A / 4A Output Current

3) Selectable 0.1Ω / 0.15Ω Internal MOSFET Switch

4) Low ESR Output Ceramic Capacitors are Available

5) Low Stanby Current during Shutdown Mode

6) 380kHz Operating Frequency

7) Feedback voltage 0.9V ±1.5% Accuracy

8) Protection circuit: Undervoltage lockout protection circuit

Thermal shutdown circuit

Overcurrent protection circuit

9) HTSOP-J8 Package (with Exposed thermal PAD)
