TPS63012  具有 2A 开关的高效率、单电感器、降压升压转换器

illustrate

 

The TPS6301x device provides a power solution powered by a two- or three-cell alkaline, nickel-cadmium or nickel-metal hydride battery, or a single-cell lithium-ion or lithium-polymer battery. Output currents can be as high as 1200 mA while using a single-cell lithium-ion or lithium-polymer battery and releasing it to 2.5 volts or less. The buck-boost converter is based on a fixed frequency, and the pulse-width modulation (PWM) controller uses synchronous rectification for maximum benefit. At low load currents, the converter enters power-down mode to maintain high efficiency over a wide range of load currents. The power-down mode can be disabled, forcing the converter to switch at a fixed frequency. The maximum average switching current is limited to a typical value of 2200 mA.

 

characteristic

 

  • Up to 96% efficiency
  • Output 3.3 buck mode step V voltage (VIN = 3.6 V to 5.5 V) current at 1200 mA
  • Up to 800 mA outputs 3.3 V in boost mode (VIN's > 2.4 V).
  • Automatic decommissioning, switching boost mode between them
  • The device quiescent current is less than 50μA
  • Input voltage range: 2 V to 5.5 V
  • Fixed and adjustable output voltage options from 1.2 V to 5.5 V
  • Power saving in low output power to improve efficiency mode
  • Force fixed frequency operation, synchronization possible
  • Load disconnects during shutdown
  • Output overvoltage protection
  • Overtemperature protection
  • Available in a small 20-pin 2.14 mm ×.93 mm WCSP package
  • apply
    • All two-cell and three-cell alkaline, nickel-cadmium or nickel-metal hydride batteries or single-cell lithium battery-powered products
    • Portable audio player
    • Pocket PC
    • Cellular
    • Personal medical products
    • White LED
