NCP1529 Adjustable Output Voltage Step-down Converter

Pin TSOP *5 Pin UDFN6 Pin Name Type Description 1 6 EN Analog Input Enable for switching regulators. This pin is active HIGH and is turned off by logic LOW on this pin. 2 2,4,7 GND Analog / This pin is the GND reference for the NFET power stage and the analog (Note 1) Power G.

Buck Converter - DC-DC, High Efficiency, Adjustable Output Voltage, Low Ripple 1.7 MHz, 1 A NCP1529 The NCP1529 step down DC DC converter is a monolithic integrated circuit for portable applications powered from one cell Li ion or three cell Alkaline/NiCd/NiMH batteries. The device is able to deliver up to 1.0 A on an output voltage range externally adjustable from 0.9 V to 3.9 V or fixed at 1.2 V or 1.35 V. It uses synchronous rectification to increase efficiency and r.
