NCP3163: Buck / Boost / Inverting Regulator, Switching, 3.4 A, 300 kHz
The NCP3163 Series is a performance enhancement to the popular MC33163 and MC34163 monolithic dc-dc converters. These Buck Boost Inverting Switching Regulators 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 controller was specifically designed to be incorporated in step-down (buck), step-up (boost), or voltage-inverting applications with a minimum number of external components. The NCP3163 Buck Boost Inverting Switching Regulator comes in an exposed pad package which can greatly increase the power dissipation of the built in power switch. An automotive qualified version is available as NCV3163.
