Overview

The Microchip MCP1624T-I/CHY is a compact, high-efficiency step-up DC-DC converter designed for portable and battery-powered applications. It features automatic PFM/PWM operation to optimize efficiency across varying load conditions, making it suitable for extending battery life in systems requiring boosted voltages. Its small SOT-23-6 package minimizes board space.

Why Choose This Part

This converter offers up to 96% typical efficiency, which is crucial for maximizing battery runtime in portable devices. Its automatic PFM/PWM operation dynamically switches modes to maintain high efficiency across light and heavy loads. The internal synchronous rectifier, compensation, and soft start features simplify design and reduce external component count.

Applications

Single-Cell Li-Ion to 3.3V/5V Systems
Efficiently boosts the voltage from a single Li-Ion battery (down to 0.8V input) to common 3.3V or 5V system rails for microcontrollers and sensors.
Portable Medical Devices
Provides a stable boosted voltage for low-power medical devices where battery life and compact size are critical, leveraging its low quiescent current.
Energy Harvesting Systems
Converts low voltage outputs from energy harvesting transducers (e.g., solar, thermoelectric) into usable higher voltages for charging or direct power.
Wearable Electronics
Powers microcontrollers and other components in wearables from compact batteries, benefiting from its high efficiency and small footprint.
PIC Microcontroller Power
Specifically suited to provide a regulated voltage source for Microchip PIC microcontrollers from a wide range of battery inputs, as indicated by its application description.
