Mingjiada Supply MPS MP2183 3A Monolithic Synchronous Step-Down Converter

Shenzhen Mingjiada Electronics Co., Ltd. — Supplier of [MPS] power management chips. Brand-new, genuine MP2183 synchronous buck converters available from stock. We support both small-batch procurement and large-volume order fulfilment, providing material supply services to the industrial, consumer electronics and portable device supply chains.

Product Overview
The MP2183 is a monolithic step-down switching regulator (synchronous step-down converter) with an integrated power MOSFET. It delivers a continuous output current of up to 3A across a wide input voltage range of 2.5V to 5.5V, whilst offering excellent load regulation and line regulation. Its output voltage is adjustable, with a minimum output of 0.6V.
The MP2183 employs a Constant On-Time (COT) control scheme to achieve fast transient response. Furthermore, the MP2183 incorporates soft-start (SS) and power-good (PG) indication functions, which help to simplify system power sequencing design.

Key Product Features
The MP2183 is a monolithic step-down switch-mode converter with an integrated power MOSFET, designed specifically for high-performance, low-power systems. Its key technical highlights are as follows:
Wide input voltage range and high output current: The MP2183 supports a wide operating input voltage range of 2.5V to 5.5V, delivering a continuous output current of up to 3A, with the output voltage adjustable down to as low as 0.6V.
Minimal Quiescent Power Consumption: The MP2183 features a quiescent current as low as 21 μA and a fixed switching frequency of 1.2 MHz, significantly extending the battery life of battery-powered devices even under light load or in standby mode.
High Reliability and Comprehensive Protection: The MP2183 incorporates internal power MOSFETs with low on-resistance of 65 mΩ and 35 mΩ; it employs a constant on-time control scheme to provide fast transient response; it also integrates external soft-start control, output overvoltage protection, short-circuit protection with hiccup mode, and a power-good signal indication function.

Typical Applications
The MP2183 is widely applicable to various low-voltage power conversion scenarios, including but not limited to:
Wireless network cards / network communication cards
Portable instruments and meters
Battery-powered devices
Low-voltage I/O system power supplies
Multifunction printers
High-performance DSP and FPGA power supplies
Consumer-grade solid-state drives (SSDs)
