TPS61130PWRG4

Overview

The TPS61130PWRG4 is a synchronous SEPIC/Flyback converter with an integrated LDO, manufactured by Texas Instruments. It features a 1.1A switch current and dual outputs: a buck-boost regulator and a linear LDO. The device operates from a 1.8V to 5.5V supply voltage range. It is housed in a 16-TSSOP package (0.173", 4.40mm wide) and supports surface mount installation. The operational temperature range extends from -40°C to 85°C. The switching frequency is fixed at 500kHz. This component is classified as a PMIC combining linear and switching regulators.

Feature Summary

• Integrates a synchronous SEPIC/Flyback converter with a 1.1A switch current capability for efficient power conversion.
• Includes an integrated Low Dropout (LDO) regulator to provide clean, stable auxiliary power alongside the main switched output.
• Supports flexible input voltage ranges suitable for single-cell battery applications and varying supply conditions.

Applications

• Power supply solutions for one-cell battery operated devices
• Systems requiring both high-efficiency buck-boost conversion and low-noise linear regulation
• Portable electronics needing compact dual-output power management

Procurement Notes

Verify the exact suffix 'PWRG4' against the manufacturer's official datasheet to confirm pinout and electrical specifications match your design requirements. Confirm RoHS compliance status and moisture sensitivity level (MSL) before assembly planning. Check for obsolescence notices or product change notifications (PCN) that may affect long-term availability or material composition. Ensure the 16-TSSOP footprint matches your PCB layout constraints.

Selection Notes

Select this component when a single IC solution is needed for both step-up/step-down conversion and a separate LDO rail. The 1.1A switch current rating determines the maximum load capacity for the primary output. Consider the 16-TSSOP package size relative to available board space. Verify that the 1.8V minimum input voltage aligns with your system's lowest operating battery voltage or supply rail.

Part Context

This part belongs to the TPS6113x family of power management ICs from Texas Instruments. These devices are designed to simplify power architecture by combining multiple regulator topologies into a single package. The TPS61130 specifically targets applications requiring a SEPIC or Flyback configuration with an additional LDO, offering a compact alternative to discrete component designs.

Replacement Considerations

Public confirmed substitute part number: ADP2140ACPZ3315R7 (Analog Devices Inc.). Verify functional compatibility and pinout alignment before substitution.
