Converter with Low Noise
Voltage Regulator Optimized
to Power Application
Processor or RF Module
The NCP1526 is a monolithic integrated circuit combining a
stepdown PWM DCDC converter and a low noise, low dropout
voltage regulator. The device is dedicated to power RF sensitive
module in portable applications from one Liion or three Alkaline /
NiCd / NiMH batteries cells. The DCDC 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 builtin 3.0 MHz (nominal) oscillator which
reduces component size by allowing the use of small inductor (down
to 1 H) and capacitors. Additional features include integrated
softstart, cyclebycycle current limiting, and thermal shutdown
protection. The integrated very low noise, low dropout regulator is
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).
