The MCP16331T-E/CH is a high-efficiency synchronous step-down DC-DC converter from Microchip Technology, designed for space-constrained applications requiring compact, low-power solutions. It operates with an input voltage range of 2.7V to 5.5V and delivers a programmable output voltage from 0.8V to 3.3V, supporting up to 1.2A continuous output current. This device integrates advanced power management features in a small 8-pin PDIP or 8-pin SOIC package, making it ideal for battery-powered and portable electronics.

Key Features

The converter achieves up to 95% efficiency with a fixed switching frequency of 1.2 MHz, enabling operation in high-density PCB layouts. It features an internal compensation scheme for simplified design, ±2% output voltage accuracy, and ultra-low quiescent current (25 μA) for extended battery life. The device includes protection features such as over-current protection (OCP), thermal shutdown, and enable/disable control for power-saving modes. Its wide input voltage tolerance accommodates unregulated power sources, while its small footprint (3.9 x 4.9 mm) reduces board space.

Applications

Primarily used in portable consumer electronics, IoT devices, and wearable technology, the MCP16331T-E/CH efficiently powers microcontrollers, sensors, and low-power peripherals. Its low noise and fast transient response make it suitable for audio and communication systems, while its robust protection features ensure reliability in automotive and industrial IoT applications.

Summary

The MCP16331T-E/CH combines high efficiency, compact design, and comprehensive protection in a cost-effective package, making it a versatile solution for low-power DC-DC conversion in battery-operated and space-constrained systems. Its broad input range and ease of use simplify integration into applications demanding reliable, compact power management.
