Low Input Voltage High Current Boost Converter Reference Design with TPS61088


Design files


This reference design delivers a very low input voltage high current boost application with a combination of the TPS61088 and the TLV61220. The TLV61220 is a low-input voltage boost converter. Its minimum input voltage is 0.7V. Setting the TLV61220’s output voltage to 5.5V to supply the TPS61088’s VIN pin can make the TPS61088 also fit for the low input voltage application.

  • Low input voltage
  • Large input current
  • Small size
  • Cost-effective
