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
-
