Overview
The NCV3064MNTXG is a monolithic power switching regulator produced by onsemi. It is part of the NCP3064 series, which is an upgrade to the popular MC33063A and MC34063A DC-DC converters. This device is designed for step-down, step-up, and voltage-inverting applications with a minimal number of external components. It features an internal temperature-compensated reference, comparator, controlled duty cycle oscillator, active current limit circuit, driver, and a high current output switch.
