NCV3063: Buck / Boost / Inverting Converter, Switching Regulator, 1.5 A

Product Description
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.
