NCP1526
400 mA, 1.2 V,
High−Efficiency, Step−Down
Converter with Low Noise
Voltage Regulator
Optimized for RF Module
The NCP1526 product is a monolithic integrated circuit combining
step−down PWM DC−DC converter dedicated to the portable
applications powered from one cell Li−ion or three cell Alkaline/
NiCd/NiMH batteries and a low noise output voltage regulator
dedicated to supply RF sensitive module in the portable applications.
The DC−DC converter operates with a fixed output voltage of
1.2 V and delivers up to 400 mA. It uses synchronous rectification to
increase efficiency and reduces external part count. The device also
has a built−in 3.0 MHz (nominal) oscillator which reduces
component size by allowing small inductor and capacitors. It
includes an integrated soft−start, cycle−by−cycle current limiting,
and thermal shutdown protection.
The additional 2.80 V very low noise, low drop output regulator, is
available with 150 mA current capability, current limitation and
overtemperature protection.
Finally, the NCP1526 is available in a space saving, ultra low
profile 3x3 mm 10 pin UDFN package (thickness 0.55 mm max).
