概述

Description

MP2164GG-Z is a Monolithic Power Systems DC-DC converter in the MP2164 family. It is a buck regulator IC with an integrated high-side switch designed for efficient step-down from a wide input to a configurable output.
Key points:
- Integrated switch (no external FET required) and feedback-based regulation
- Adjustable output via external resistors; fixed-frequency operation
- Built-in protections: undervoltage lockout,-overcurrent/short-circuit protection, thermal shutdown
- Soft-start and enable control for reliable startup
- RoHS-compliant GG package
Typical uses:
- Vehicle and industrial power rails, consumer electronics, and LED driver applications where a compact, efficient step-down regulator is needed.
Notes:
- For exact electrical specs (input range, output accuracy, switching frequency, quiescent current) and recommended application circuits, consult the MP2164GG-Z datasheet.

Features

Here are the typical features of MP2164GG-Z (concise):
- Buck regulator with integrated high-side MOSFET
- Wide input range: up to 42 V
- Output current capability: up to ~4 A (switch current)
- Current-mode control for fast transient response
- Adjustable output via external resistor divider (standard feedback)
- Soft-start to minimize inrush
- Enable/shutdown control
- Protection: overcurrent/short-circuit (often with hiccup), overtemperature, and undervoltage lockout
- Efficient operation with light-load modes (PWM/PFM behavior)
- RoHS-compliant, compact packaging (GG-Z variant) suitable for wide applications
Note: Exact numbers and internal features may vary by revision; refer to the datasheet for precise specs.

Package

MP2164GG-Z is in a 16‑pin QFN package (3.0 × 3.0 mm) with an exposed pad; RoHS compliant.

Pinout

- Pin count: 8 pins (8-pin package)
- Function: High‑efficiency buck (step‑down) switching regulator. Converts Vin to a lower regulated Vout using a switching node (SW/LX), with feedback (FB) for regulation and pins for VIN, GND, EN (enable), and compensation/bypass as part of its control.

Manufacturer

Manufacturer: Monolithic Power Systems, Inc. (MPS).
They are a fabless semiconductor company that designs and markets analog and mixed-signal power-management ICs (e.g., DC-DC converters, PMICs) for applications in computing, networking, consumer electronics, and automotive.

Application

- CPU/GPU and other point-of-load VRMs on desktops, laptops, and graphics cards
- Distributed power for motherboards, servers, and networking gear
- Telecom and data-communication equipment power supplies
- Industrial control, automation, and related power rails
- Automotive electronics and battery-powered devices
- LED backlight/display power rails

Equivalent

There is no widely published exact pin‑for‑pin cross reference for MP2164GG‑Z. For functionally similar replacements, look for 4A buck regulators in an 8-pin package with 4–40V input range, e.g., Richtek RT8250/RT8253, TI LM3671/LM2675 family, Analog Devices ADP2302/ADP2303. Always verify pinout, input/output voltage ranges, and current rating before substitution.
