module in portable applications from one Li?ion or three Alkaline /
NiCd / NiMH batteries cells. The DC?DC converter offers fixed
output voltage and delivers up to 400 mA. It uses synchronous
rectification to increase efficiency and eliminates the external

Schottky diode.
The device also has a built?in 3.0 MHz (nominal) oscillator which
reduces component size by allowing the use of small inductor (down
to 1 m H) and capacitors. Additional features include integrated
soft?start, cycle?by?cycle current limiting, and thermal shutdown

available with 150 mA current capability, current limitation and
temperature limit protection.
The NCP1526 is available in a space saving, ultra low profile
3x3 mm, 10 pin UDFN package (thickness 0.55 mm max).
