MicroSiP 3 W Step-Up Converter

Texas Instruments' 3 W high-efficiency step-up converter in MicroSiP™ packaging

MicroSiP™ 3 W Step-Up ConverterTexas Instruments' TPS8125x device is a complete MicroSiP DC/DC step-up power solution intended for battery-powered portable applications. Included in the package are the switching regulator, inductor, and input/output capacitors. Only a tiny additional output capacitor is required to finish the design. 

The TPS8125x is based on a high-frequency synchronous step-up DC/DC converter optimized for battery-powered portable applications. The DC/DC converter operates at a regulated 4 MHz switching frequency and enters power-save mode operation at light load currents to maintain high efficiency over the entire load current range.

Features Applications
  • 91% efficiency at 4 MHz operation
  • ±2% total DC voltage accuracy
  • 43 µA supply current
  • Wide VIN range from 2.5 V to 5.5 V
  • Cell phones, smart-phones, and tablet PCs
  • Mono and stereo APA applications
  • USB-OTG, HDMI applications
  • USB charging Port (5 V)
