概述

Description

MP5017GD-Z is a Monolithic Power Systems DC-DC buck regulator IC. It’s a synchronous, fixed‑frequency step‑down converter with integrated high‑ and low‑side MOSFETs, designed to convert a higher input voltage to a regulated lower output with high efficiency. It uses PWM control, includes soft-start, enable, and protection features (overcurrent, thermal, undervoltage/overvoltage as applicable). The “GD‑Z” suffix indicates RoHS/green packaging with tape‑and‑reel options. Typical uses include power management for CPUs/FPGA/SoCs, memory rails, automotive electronics, LED drivers, and other compact, efficient DC‑DC supplies. For exact input voltage range, output voltage options, current capability, switching frequency, and external components, consult the MP5017GD‑Z datasheet and reference designs.

Features

Key features of MP5017GD-Z (concise):
- Wide input range: supports 4.5V to 42V
- Synchronous buck regulator with integrated high-side/low-side MOSFETs
- High efficiency (up to about 95% in typical apps)
- Current-mode control with fast transient response
- Soft-start to prevent inrush and output overshoot
- Adjustable output via feedback network
- Enable/shutdown control pin
- Comprehensive protection: overcurrent/short-circuit, overvoltage (OVP), thermal shutdown (TSD/OTP), undervoltage lockout (UVLO)
- Suitable for automotive/industrial environments; accurate regulation over temp
- Small, lead-free package (GD-Z variant) for compact designs
Note: exact switching frequency and additional features may vary by package/variant; consult the datasheet for precise specs.

Package

MP5017GD-Z is in a lead-free QFN package, 20 pins, about 4×6 mm (RoHS-compliant).

Pinout

MP5017GD-Z is a Monolithic Power Systems 16-pin, QFN-format synchronous buck regulator. It includes integrated high‑ and low‑side MOSFETs and uses an inductor and feedback network to generate a regulated output from VIN.
Typical pin functions (16 pins total):
- VIN: input supply
- GND: ground
- SW: switch node to inductor
- BST: bootstrap for high‑side gate drive
- EN: enable
- FB: feedback for regulating VOUT
- ILIM: current-limit adjustment
- RUN/SS: soft-start/run control
- PGOOD: power‑good status
- VCC or bias pin: device bias supply
- COMP: external compensation
- NC: no connect (unused pins)
Note: exact pin-to-pin mapping can vary by package variant; consult the specific datasheet for the MP5017GD-Z you’re using to confirm the exact pinout.
