概要

Description

MP2357DT-LF-Z is a high-efficiency, synchronous buck regulator IC from Monolithic Power Systems. It integrates power MOSFETs and a fixed-function control circuit to convert a higher input voltage to a lower, stable output for DC power in portable and consumer electronics.
Key features (typical):
- Integrated high-side and low-side MOSFETs for a compact solution
- PWM/PFM control for efficient operation across load conditions
- Protection: undervoltage, overcurrent, overtemperature, and short-circuit safeguards
- Adjustable output via external resistor divider; enable/shutdown control
- Suitable for compact point-of-load power architectures
- Lead-free, RoHS-compliant LF package (e.g., DFN/QFN style)
Typical applications:
- Point-of-load regulators in laptops, tablets, smartphones, set-top boxes
- Small embedded power supplies and other compact DC-DC programs
For exact electrical specs (input range, switching frequency, max output current, efficiency) and pinout, refer to the MP2357DT-LF-Z datasheet.

Features

MP2357DT-LF-Z is a high-efficiency synchronous buck regulator. Key features:
- Output: up to ~4A continuous current
- Input range: wide (suitable for 4.5V–28V automotive/dc supply)
- Output: adjustable (0.8V to ~20V) via external resistors
- Switching frequency: around 1.5 MHz (compact solution, good transient response)
- Control: current-mode PWM for fast regulation and stability
- topology: integrated high-side and low-side MOSFETs
- Efficiency: high, typical up to ~95% depending on conditions
- Protections: over-current/short-circuit with hiccup, over-temperature, UVLO/ undervoltage lockout
- Features: soft-start, enable/shutdown pin, feedback/IMON options for sensing
- package: lead-free LF version in compact 8-pin DFN/SOIC-type package
Note: exact input range and current rating can vary by variant; confirm from the datasheet for your specific application.

Package

DFN-8 (8-pin) package, 3×3 mm, lead‑free.

Pinout

- Pin count: 8 pins
- Function: MP2357DT-LF-Z is a synchronous buck (step-down) DC-DC regulator with integrated high- and low-side MOSFETs. It provides a regulated lower output from a higher input, featuring adjustable output via feedback, enable/soft-start, and protection (over-current).

Manufacturer
