Product Overview

MP1653AGTF-Z launched by MPS (Monolithic Power Systems) is a high-performance synchronous buck converter belonging to the DC-DC power management IC series. It adopts advanced synchronous rectification technology to achieve a conversion efficiency of up to 95%, and integrates rich protection functions. With an ultra-small package size, it meets the power requirements of various portable and space-constrained devices, making it an ideal choice in the field of high-efficiency power chips.

Key Features

• Ultra-High Conversion Efficiency：Efficiency reaches 95% under conditions of 12V input, 5V output, and 3A load, significantly reducing energy loss and heat dissipation pressure.
• Wide Input Voltage Range：Supports 4.5V to 24V wide input, compatible with lithium batteries, adapters and other power supply methods, suitable for multi-scenario power design.
• Ultra-Small Package Design：Adopts QFN-10 (3mmx3mm) package, saving PCB space, ideal for portable devices and high-density layout small-package power IC applications.
• Comprehensive Protection Mechanism：Integrates over-current protection (OCP), over-temperature protection (OTP), under-voltage lockout (UVLO) and short-circuit protection (SCP) to improve system reliability.
• Flexible Output Regulation：Output voltage can be adjusted to 0.8V-15V via external resistors, supporting 3A continuous output current to meet voltage requirements of different loads.

Technical Specifications

Typical Applications

• Portable Electronic Devices：As the core power management unit, it supplies power to peripheral modules of laptops and tablets. The wide input range adapts to different adapters, and the high-efficiency feature extends device battery life.
• IoT Terminals：In smart sensors and wireless communication devices, the DC-DC converter stably outputs low-voltage DC power, and the small package design saves limited internal space of devices.
• Industrial Control Equipment：Provides stable voltage for PLC modules and motor drive circuits. The wide temperature operating range and over-current protection ensure reliable operation of power systems in industrial environments.
• Consumer Electronics：In smart home controllers and security cameras, the flexible output adjustment function provides precise voltage for different chips (such as MCU, sensors), reducing design complexity.
• Automotive Electronic Auxiliary Devices：Adapts to car chargers and driving recorders. 4.5V-24V input is compatible with car power fluctuations, and protection mechanisms prevent damage to devices caused by voltage abnormalities.

Why Choose MP1653AGTF-Z？

• High Efficiency and Energy Saving：95% conversion efficiency reduces energy waste and lowers device heat dissipation requirements, suitable for power-sensitive portable devices.
• Wide Adaptability：4.5V-24V wide input voltage covers most power scenarios, and 0.8V-15V adjustable output meets diverse load requirements.
• Space Optimization：3mmx3mm QFN package is a typical representative of small-package power ICs, significantly reducing the volume of power modules and improving PCB layout flexibility.
• Multiple Protections：Comprehensive protection functions avoid damage to devices caused by over-current, over-temperature and other abnormalities, enhancing long-term operation stability of the system.
• Simplified Design：Integrated synchronous rectifiers and protection circuits reduce the number of external components, shortening the design cycle of power circuits.
