Semtech TS32101

High Efficiency DC/DC Boost Converter for USB, 2Mhz

Add to Watch List

The TS32101 is a DC/DC synchronous switching Boost Converter with fully integrated power switches, internal PWM current mode compensation, and full fault protection. The switching frequency of 2 MHz was chosen to enable the use of small external components for portable applications. The device also has a constant output current limit loop to provide a sharp output current limit that doesn’t move significantly with input voltage and output voltage.


  • Output up to 1.5A at 5.0V with 1.8V input
  • Wide input voltage range: 1.75V – 5.0V
  • Output current up to 2A
  • Robust operation during hot-load disconnect and hot-load disable
  • Adjustable output voltage up to 5.5V
  • Adjustable output current limit
  • Includes full output isolation/reverse current blocking when disabled
  • 2 MHz ± 10% fixed switching frequency
  • Low power mode
  • High efficiency – up to 95%
  • Full protection for over-current, overtemperature, VOUT over-voltage, and VIN under-voltage
  • Power good/fault indication


  • USB power
  • Portable products
  • Wireless remote sensors
  • Emergency chargers
