NCP1523BGEVB:NCP1523B Step Down DC-DC Converter Evaluation Board
The NCP1523B step-down PWM DC-DC converter is optimized for portable applications powered from one cell Li-ion or three cell Alkaline/NiCd/NiMH batteries. The device is available in an adjustable output voltage from 0.9 V to 3.3 V. It uses synchronous rectification to increase efficiency and reduce external part count. The device also has a built-in 1.5 MHz (nominal) oscillator which reduces component size by allowing a small inductor and capacitors. Available in PWM mode only (NCP1523BFCT2G), it offers a very efficient load transient solution. Finally, it includes an integrated soft-start, cycle-by-cycle current limiting, and thermal shutdown protection. The NCP1523B is available in a space saving, 8 pin chip scale package. The NCP1523BGEVB evaluation board provides a platform for quick evaluation of the NCP1523B device. It features an enable pin as well as jumpers for selecting the output voltage.
