概述

Description

MP28163GQ-Z is a Monolithic Power Systems MP28163GQ-Z high-efficiency buck DC-DC converter. It integrates the control circuitry and power MOSFETs to step down a higher input voltage to a lower, programmable output, suitable for automotive, industrial, and general purpose power-supply applications. Key features typically include a wide input range, adjustable output via an external resistor divider, fixed switching frequency, enable/shutdown control, soft-start, and protections (overcurrent/short-circuit, overtemperature, undervoltage). It is packaged in a GQ (QFN-like) package with RoHS-compliant -Z suffix. Typical usage requires external inductor, input and output capacitors, and a feedback network; a catch diode is only needed if operating in a non-synchronous mode. For exact specs, pinout, and reference designs, consult the MP28163GQ-Z datasheet.

Features

Here are the typical features of MP28163GQ-Z (concise):
- Wide input voltage range (suitable for automotive/LED apps)
- Integrated high-side switch for a buck/step-down regulator
- Constant-current LED driver with adjustable output current
- Dimming support: PWM and/or analog dimming
- Internal protections: overcurrent/short-circuit, thermal shutdown
- Input undervoltage lockout and enable/shutdown control
- Soft-start to reduce inrush and prevent overshoot
- Fixed switching frequency with efficient operation
- Small 8-pin QFN package with exposed pad (thermal capability)
Note: exact electrical specs (voltage range, current capability, switching frequency) can vary; please consult the latest datasheet for precise numbers.

Package

The MP28163GQ-Z comes in a 16‑pin QFN package (GQ = QFN, 3.0 mm × 3.0 mm). The “-Z” suffix denotes tape-and-reel, RoHS‑compliant shipping.
