概述
Description
ADP3624ARHZ-RL is Analog Devices’ quad-channel DC-DC buck regulator part (from the ADP3624 family). It combines four high-efficiency synchronous buck regulators in one RoHS-compliant package, enabling multiple low-voltage rails from a common higher input. Typical features include integrated high/low side MOSFETs, programmable output voltages, enable/soft-start, and protection functions (UVLO, overcurrent, thermal shutdown). It’s suited for automotive/industrial power-management and multi-rail designs where space and efficiency matter. Exact specs (input range, per-channel current, switching frequency, pinout, and packaging) are in the official datasheet for ADP3624ARHZ-RL, so consult that document for precise details.
Features
Here are the typical features of ADP3624ARHZ-RL (data sheet should be consulted for exact specs):
- Dual synchronous buck regulator with integrated MOSFETs
- Wide input voltage range suitable for automotive/industrial applications
- High efficiency across load conditions
- Current-mode control with adjustable switching frequency
- Soft-start and programmable operating mode
- External feedback for precise output voltage (adjustable Vout)
- Enable/shutdown control and status/power-good signaling
- Robust protection: UVLO, overcurrent/short-circuit, overtemperature
- Remote-sense capability and good EMI/ESD performance
- Fault reporting and diagnostic options
- RoHS-compliant packaging; Tape & Reel (ARHZ-RL)
Note: For exact electrical specs, pinout, and ordering details, refer to the official ADI datasheet.
