Product Overview

The TPS61251DSGT is a Boost Converter for battery backup charging with adjustable constant current and snooze mode. The device provides a power supply solution for products powered by either a three-cell, NiCd/NiMH battery or one-cell Li-ion/Li-polymer battery. The wide input voltage range is ideal to power portable applications like mobile phones, solid state drives (SSD) and wireless modems. The converter is designed to charge large capacitors in the Farad range to support battery backup applications. During capacitor charging, the TPS61251 device is working as a constant current source until VOUT has reached its programmed value. The charge current can be programmed by an external resistor RILIM and provides a ±10% accuracy for the average input current limit.
  • Resistor programmable input current limit
  • Snooze mode draws only 2μA (typical) quiescent current
  • Designed to charge large capacitor values in the Farad range
  • Power good indicates appropriate output voltage level even in shut down
  • 100% Duty-cycle mode when VIN>VOUT
  • Load disconnect and reverse current protection
  • Short-circuit protection
  • Up to 92% efficiency
  • Green product and no Sb/Br
