Overview

The NCP1522B step- down DC-DC converter is a monolithic integrated circuit optimized for portable applications powered from one cell Li- Ion or three cell Alkaline/NiCd/NiMH batteries. The part, available in adjustable output voltage versions ranging from 0.9 V to 3.3 V, is able to deliver up to 600 mA. It uses synchronous rectification to increase efficiency and reduce external part count. The device also has a built- in 3 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 NCP1522B is available in a space saving, low profile TSOP5 and UDFN6 packages.

  • Power supply for application processor
  • Power supply for processor with low core voltage

  • Cellular phones, smart phones, and PDAs
  • MP3 players and portable audio systems
  • Digital still cameras and video cameras

  • 94% efficiency, 50 uA quiescent current, 0.3 uA shutdown current
  • 3.0 MHz switching frequency
  • Auto-switching between PWM and PFM mode at light load conditions
  • Adjustable output voltage from 0.9V to 3.3V

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
