Details
The NCP1521B step-down PWM DC-DC converter is optimized for portable applications powered from one cell Li-ion or three cell Alkaline/NiCd/NiMH batteries. The part is available in adjustable output voltage versions ranging from 0.9 V to 3.3 V. It uses synchronous rectification to increase efficiency and reduce external part count. The device also has a built-in 1.5 MHz (nominal) oscillator which reduces component size by allowing smaller inductors and capacitors. Automatic switching PWM/PFM mode offers improved system efficiency. Additional features include integrated soft-start, cycle-by-cycle current limiting and thermal shutdown protection. The NCP1521B is available in space saving, low profile TSOP5 and UDFN6 packages.
Key Features
- Wide input voltage range from 3.6V to 36V
- Adjustable output voltage range from 1.225V to 11V
- Fixed output options of 1.8V, 2.5V, 3.3V, 5V
- Low dropout voltage of 400mV @ 500mA output
- Low quiescent current of 60μA
- Current limit and thermal shutdown protection
Application
- Power supply for application processor
- Power supply for processor with low core voltage
