3-A peak current high-efficiency ultra-small solution size buck-boost converter

Overview

TopologyBuck-Boost Converter
Input voltage1.6-5.5 V
Output 15.5 V
IC revision00

Description

The TPS631010 and TPS631011 are constant frequency peak current mode control buck-boost converters in tiny wafer chip scale package. They have a 3A peak current limit (typical) and 1.6V to 5.5V input voltage range and provide a power supply solution for system pre-regulators and voltage stabilizers.

Features

  • 1.6V to 5.5V input voltage range
  • Device input voltage > 1.65V for start-up
  • 1.2V to 5.5V output voltage range(adjustable)
  • 1.0V VOUT is supported in PFM mode
  • High output current capability, 3A peak switch current
  • 2A output current for VIN ≥ 3V, VOUT = 3.3V
  • 1.5A output current for VIN ≥ 2.7V, VOUT = 3.3V
  • Active output discharge (TPS631011 only)
  • High efficiency over the entire load range
  • 8μA typical quiescent current
  • Automatic power save mode and forced PWM mode configurable
  • Peak current buck-boost mode architecture
  • Seamless mode transition
  • Forward and reverse current operation
  • Start-up into pre-biased outputs
  • Fixed-frequency operation with 2MHz switching
  • Safety and robust operation features
  • Overcurrent protection and short-circuitprotection
  • Integrated soft start with active ramp adoption
  • Overtemperature protection and overvoltageprotection
  • True shutdown function with load disconnect
  • Forward and backward current limit
  • Small solution size
  • Small 1-µH inductor
  • 1.803mm × 0.905mm in WCSP

Typical applications

  • Fingerprint, camera sensors (electronic smart lock, IP network camera)
  • Voltage stabilizer (datacom, optical modules, cooling/heating), System pre-regulator (smartphone, tablet, terminal, telematics), Point-of-load regulation (wired sensor, port/cable adapter, and dongle)
