Descriptions:

The TPS61220 is a synchronous boost converter designed for low-power applications. It is optimized for energy harvesting and battery-powered systems, providing a regulated output from very low input voltages (as low as 0.7V).

Features:

  • Ultra-low Start-up Voltage: 0.7V
  • Automatic Power Path Management (seamless switch between input sources)
  • True Disconnect in Shutdown Mode (output fully disconnected from input)
  • Forced PWM Mode & Power Save Mode for efficiency optimization
  • Overvoltage Protection (OVP)
  • Thermal Shutdown Protection

This IC is commonly used in energy harvesting, wireless sensors, and portable electronics where low input voltage operation is critical.
