Description

MP2452DD-LF-Z is a dual synchronous buck regulator IC from Monolithic Power Systems. It combines two high-efficiency step-down regulators in a compact package to generate two stable rails from a single input, suitable for space‑constrained portable electronics.
Key points:
- Two integrated buck regulators with external feedback (adjustable voltages).
- Integrated high‑ and low‑side MOSFETs for high efficiency.
- Features often include enable/shutdown control, soft-start, current limit, over‑temperature protection, and UVLO.
- Used to derive core and I/O rails in devices like smartphones, cameras, wearables, and other compact systems.
The -LF-Z suffix denotes a specific lead-free, RoHS-compliant packaging variant used by MPS (exact package/pinout and electrical specs are in the official datasheet). For precise electrical specs, recommended operating conditions, and pinout, consult the datasheet and product page.

Package

MP2452DD-LF-Z comes in an 8-pin DFN package (3×3 mm) with a bottom exposed pad; lead-free (LF) and RoHS-compliant, suitable for surface-mount applications.

Pinout

Pin count: 12 pins (QFN-12).
Function: Monolithic Power Systems MP2452DD-LF-Z is a synchronous buck (step-down) DC-DC converter with integrated high-side/low-side MOSFETs for efficient voltage regulation (adjustable output via feedback, with enable/soft-start features).

Manufacturer

Manufacturer: Monolithic Power Systems (MPS).
Company type: A fabless semiconductor company that designs and markets high-performance analog and mixed-signal integrated circuits, specializing in power-management ICs (e.g., DC-DC converters, regulators, controllers). It is publicly traded on NASDAQ under the ticker MPWR.

Application

MP2452DD-LF-Z is a high-efficiency DC-DC buck regulator in a lead-free, compact package. Applications: power management in battery-powered and portable devices (phones, tablets, wearables); point-of-load rails for MCUs, CPUs, FPGAs/ASICs; telecom/networking equipment (routers/modems); set-top boxes, printers, and other consumer electronics; industrial/instrumentation systems needing compact, efficient buck regulation.
