NCP3063: Boost / Buck / Inverting Converter, Switching Regulator, 1.5 A

This Buck Boost Inverting Switching Regulator consists of an internal temperature compensated reference, comparator, controlled duty cycle oscillator with an active current limit circuit, driver and high current output switch. New features include an internal thermal shutdown protection and cycle-by-cycle current limit. This series was specifically designed to be incorporated in step-down (buck) and step-up (boost) and voltage-inverting applications with a minimum number of external components. The NCV3063 is available for automotive applications. See NCP3064 for product with ENABLE feature.

Features

Operation up to 40 V Input
Frequency operation up to 150 KHz
Internal thermal Shutdown with hysteresis
Cycle-by-Cycle Current Limiting
Excel Based Design Tool

Benefits
