TPS631000 - High Power Density Buck-Boost Converter

Description

The TPS631000 is a constant frequency peak current mode control buck-boost converter.

The device has a 3-A peak current limit (typical) and 1.6-V to 5.5V input voltage range.

The TPS631000 provides a power supply solution for system pre-regulators and voltage stabilizers.

Features

  • 1.6-V to 5.5-V input voltage range.
  • Device input voltage > 1.65 V for start-up.
  • 1.2-V to 5.3-V output voltage range (adjustable).
  • High output current capability, 3-A peak switch current.
  • 2-A output current for VIN ≥ 3 V, VOUT = 3.3 V.
  • 1.5-A output current for VIN ≥ 2.7 V, VOUT = 3.3 V.
  • High efficiency over the entire load range.
  • 8-μA typical quiescent current.
  • Power save mode.
  • 150-mV load-step response at.
