Package:TO220F-5L

A chopper type switching regulator IC which provides various features and protection functions required for a step-down switching regulator.
The output is fixed at Vo=5V, but voltage can become variable by adding 2 external resistors (applies only for voltage increase)
A highly efficient switching regulator can be constructed with only 5 external components.

Features

    Compact full mold package (TO220)
    ・Output current: 5.5A
    ・High efficiency: 83%typ (at Vo=5V)
    ・Requires only 4 discrete components
    ・Built-in reference oscillator (150kHz)
    ・Built-in drooping-type-overcurrent and thermal protection circuits
    ・Soft start available by ON/OFF pin

Application

    ・On-board local power supply
    ・OA equipment
