STMICROELECTRONICS DC/DC Controller DIP8

This monolithic control circuit delivers the main functions for DC-to-DC voltage conversion. The device contains an internal temperature compensated reference, a comparator, and a duty cycle controlled oscillator with an active current limit circuit, a driver, and a high current output switch.

The output voltage is adjustable through two external resistors, providing a precise 2% reference accuracy. Employing a minimum number of external components, this device is specifically designed for step-down, step-up, and voltage-inverting applications, making it highly versatile for various power management needs.

Key Features

• Internal temperature compensated reference
• Active current limiting at 2.5mA
• Typical low quiescent current
• High current output switch

Applications

• Power management
• Step-down (Buck) converters
• Step-up (Boost) converters
• Voltage-inverting applications

With a wide input voltage range of 3V to 40V and an efficiency of up to 89%, this controller is suitable for a variety of power conversion requirements. The DIP8 package allows for straightforward through-hole mounting on printed circuit boards, operating reliably between 0°C and 70°C. It features compact dimensions of 43 mm x 33 mm x 15 mm and a lightweight design of just 0.47 grams.
