TPSM83103 Datasheet 1.2a Output Current Buck-boost Module

Manufacturer: Texas Instruments

Overview: TPSM83102 SLVSH13A – AUGUST 2024 – REVISED JANUARY 2025 TPSM83102 and TPSM83103 1.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The TPSM83102 and TPSM83103 are constant frequency peak current mode control buck-boost converters in samll μSiP module package.

It has 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.

Depending on the input voltage, the TPSM83102 and TPSM83103 automatically operate in boost, buck, or in 3-cycle buck-boost mode when the input voltage is approximately equal to the output voltage.

Key Features

  • 1.6V to 5.5V input voltage range.
  • Device input voltage > 1.65V for start-up.
  • 1V to 5.5V output voltage range(adjustable).
  • High output current capability, 3A peak switch current.
  • 1.5A output current for VIN ≥ 3V, VOUT = 3.3V.
  • 1.2A output current for VIN ≥ 2.7V, VOUT = 3.3V.
  • High efficiency over the entire load range.
  • 8μA typical quiescent current.
  • Automatic power save mode and forced PWM mode configurable.
