Overview
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 reduce external part count.
The device also has a built−in 1.
7 MHz (nominal) oscillator which reduces component size by allowing a small inductor and capacitors.
Automatic switching PWM/PFM mode offers improved system efficie...
