Aperçu du produit

The TPS61071DDCR is a synchronous Boost Converter with for use with 600mA switch. The TPS6107x device provides a power supply solution for products powered by either one-cell, two-cell or three-cell alkaline, NiCd/NiMH or one-cell Li-ion/Li-polymer battery. Output current can go as high as 75mA while using a single-cell alkaline and discharge it down to 0.9V. It can also be used for generating 5V at 200mA from a 3.3V rail or a Li-ion battery. The boost converter is based on a fixed frequency, pulse-width-modulation (PWM) controller using a synchronous rectifier to obtain maximum efficiency. The power-save mode is disabled in the TPS61071, forcing the converters to operate at a fixed switching frequency. The TPS6107x output voltage is programmed by an external resistor divider. The converter can be disabled to minimize battery drain. During shutdown, the load is completely disconnected from the battery.
  • Power-save mode version available for improved efficiency at low output power
  • Load disconnect during shutdown
  • Over-temperature protection
  • 90% Efficiency
  • 19µA Typical quiescent current
  • Green product and no Sb/Br
