Descripción general

Description

MP28115DQ-LF-Z is a Monolithic Power Systems DC-DC buck regulator IC used to step down a higher input voltage to a stable lower output. It is designed for high-efficiency power conversion in processors, telecom, consumer, and industrial supplies.
Key points:
- Type: buck regulator IC (often used with synchronous rectification; check variant for integrated/external FETs)
- Control: fast transient response with programmable switching frequency and adjustable output
- Protections: undervoltage lockout, overcurrent/short-circuit protection, thermal shutdown
- Packaging: RoHS-compliant lead-free variant (-LF, -Z)
- Applications: Vcore/VDD rails, other low-voltage power rails requiring compact, efficient regulation
Note: Exact specs (Vin range, Vout range, Iout capability, switching frequency, pinout) vary by variant. Refer to the official MP28115DQ-LF-Z datasheet and application notes for precise electrical characteristics and recommended circuit diagrams.

Features

Here are the typical features of MP28115DQ-LF-Z (Monolithic Power Systems):
- 15 A continuous output current with integrated high-side MOSFET (synchronous buck)
- High-efficiency operation with synchronous rectification
- Wide input voltage range suitable for multi-rail automotive/industrial applications
- Flexible switching: selectable fixed frequency and/or PWM/PFM modes for light-load efficiency
- Current-mode control with cycle-by-cycle current limit
- External feedback for adjustable output voltage; supports standard resistor divider
- Soft-start to limit inrush and prevent overshoot
- Enable/Shut-down input for programmable on/off control
- Protective functions: undervoltage lockout, overvoltage protection, thermal shutdown
- Overcurrent/short-circuit protection (often with hiccup behavior)
- RoHS-compliant, lead-free (LF-Z) package; 16-pin QFN (compact footprint)
Note: exact electrical ranges (input, output voltage range, switching frequency) are defined in the official datasheet; verify for your design.

Package

MP28115DQ-LF-Z is supplied in MPS’s DQ package — a lead‑free (LF) QFN/DFN-style (no‑lead) package. For exact pin count, pad layout and dimensions refer to the MP28115 datasheet.

Manufacturer

The MP28115DQ-LF-Z is manufactured by Monolithic Power Systems (MPS). MPS is a fabless semiconductor company that designs and sells high-efficiency power-management integrated circuits and power-conversion solutions for applications in computing, communications, industrial, automotive and consumer electronics.

Application

Applications for MP28115DQ-LF-Z include:
- High-efficiency DC-DC conversion for power rails in notebooks/tablets and telecom equipment
- LED backlight and general LED lighting drivers
- Automotive power management and in-vehicle electronics
- Industrial control systems and power supplies
- Battery-powered portable devices and consumer electronics
- USB/PD power management and charger circuits
(DS/errata: confirm exact datasheet for precise use cases.)

Equivalent

I can’t find a reliable datasheet for MP28115DQ-LF-Z. To recommend true equivalents I need its key specs (input voltage range, max output current, switching topology—synchronous buck/LDO, switching frequency, adjustable/fixed output, package). Provide the datasheet or those specs and I’ll list close cross‑references (TI, Analog Devices, Microchip, Richtek, etc.) in one short reply.
