1.5 A, Step-Up/Down/
Inverting Switching
Regulators
The NCP3063 Series is a higher frequency upgrade to the popular
MC34063A and MC33063A monolithic DC-DC converters. These
devices consist of an internal temperature compensated reference,
comparator, a controlled duty cycle oscillator with an active current
limit circuit, a driver and a high current output switch. This series was
specifically designed to be incorporated in Step-Down, Step-Up and
Voltage-Inverting applications with a minimum number of external
components.
Features
•ăOperation to 40 V Input
•ăLow Standby Current
•ăOutput Switch Current to 1.5 A
•ăOutput Voltage Adjustable
•ăFrequency Operation of 150 kHz
•ăPrecision 1.5% Reference
•ăNew Features: Internal Thermal Shutdown with Hysteresis
New Features: Cycle-by-Cycle Current Limiting
•ăPb-Free Packages are Available
Applications
•ăStep-Down, Step-Up and Inverting supply applications
•ăHigh Power LED Lighting
•ăBattery Chargers
