ONSEMI NCP1597AMNTWG Synchronous Buck Regulator
The NCP1597A is a high-frequency synchronous buck regulator designed for efficient power conversion in portable and electronic applications. Utilizing a fixed 1 MHz switching frequency, it integrates both high-side P-channel and low-side N-channel MOSFETs capable of delivering up to 2.0A. Featuring internal soft-start, cycle-by-cycle current limiting, thermal shutdown, and power saving modes, it ensures fast transient response and stability. The device operates from 4.0V to 5.5V input and offers adjustable output voltages as low as 0.8V, making it ideal for DSP power supplies, computer peripherals, LCD TVs, and networking equipment.
