MC34063A Boost Module

The MC34063A Boost Converter Module is a compact, adjustable step-up voltage regulator that converts low DC input voltages (3.6V–30V) to a higher output voltage (3.8V–36V). It is based on the reliable MC34063A DC-DC converter IC, commonly used in battery-powered and low-voltage electronics where an increase in voltage is needed.

With a built-in adjustable potentiometer, this module makes it easy to dial in your desired output voltage, making it ideal for powering higher-voltage components or microcontrollers from lower-voltage power supplies.

Key Features:

• Step-Up Function: Boosts lower DC voltages to higher, adjustable levels

• Adjustable Output: Easily set output voltage using onboard potentiometer

• Compact Design: Fits in small spaces for portable and embedded applications

• Built-In Switching Regulator: Based on the reliable MC34063A IC

• Safe Power Output: Ideal for powering sensors or small electronics with controlled current draw

Specifications:

• Input Voltage Range: 3.6V to 30V DC

• Adjustable Output Voltage: 3.8V to 36V DC
