| Part Number | MP2144GJ-Z |
|---|---|
| Manufacturer | Monolithic Power Systems (MPS) |
| Category | DC-DC Switching Regulators; Synchronous Step-Down Buck Converters |
| Description | 18V Input 1A Ultra-Small Synchronous Buck Converter, High Efficiency, TSOT23-8 Package |
Product Overview
The MP2144GJ-Z is a high-efficiency, fully synchronous step-down buck converter optimized for compact, low-power portable electronics and space-constrained embedded systems. It operates from a wide 2.5V to 18V input voltage range and delivers up to 1A continuous output current with excellent load and line regulation. The device integrates internal power MOSFETs to minimize external components, uses current-mode control for fast transient response, and includes PFM mode to maximize efficiency at light loads. Comprehensive built-in protections (OCP, OVP, OTP, UVLO) ensure safe and reliable operation in demanding applications. Housed in an ultra-compact TSOT23-8 package, it enables high-density PCB design for portable and battery-powered devices.
