RT34063A

Update Alert Share

The RT34063A Series is a monolithic control circuit containing the primary functions required for DC-DC converters.

These devices consist of an internal temperature compensated reference, comparator, controlled duty cycle oscillator with an active current limit circuit, driver and high current output switch.

This series was specially designed to be incorporated in step-down and step-up and Voltage-inverting applications with a minimum number of external components.

Applications

  • Saver for Cellular Phones
