Overview
The NCV3064DR2G, produced by onsemi, is a monolithic power switching regulator designed for DC-DC converter applications. It is an upgrade to the popular MC33063A and MC34063A monolithic DC-DC converters, offering higher frequency operation and enhanced features. This device is optimized for step-down, step-up, and voltage-inverting converter applications with a minimal number of external components.
The NCV3064 series includes internal temperature-compensated reference, comparator, controlled duty cycle oscillator, active current limit circuit, driver, and high current output switch. It also features a low power shutdown mode and logic level shutdown capability, making it suitable for a wide range of applications, including high power LED lighting and battery chargers.
