Semtech TS32101

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

Overview

TopologyBoost Converter
Input voltage1.8-5.5 V
Switching frequency1800-2200 kHz
Output 15.5 V / 2 A
IC revision2.1

Description

The TS32101 is a DC/DC synchronous switching BoostConverter with fully integrated power switches, internal PWMcurrent mode compensation, and full fault protection. Theswitching frequency of 2 MHz was chosen to enable the useof small external components for portable applications. Thedevice also has a constant output current limit loop to providea sharp output current limit that doesn’t move significantlywith input voltage and output voltage.

Features

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

Typical applications

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