Overview
The TPS61132RSAR is a dual-output power management IC from Texas Instruments, housed in a 16-VQFN package. It integrates a SEPIC converter and a buck-boost or linear regulator to support dual-cell battery systems. The device operates with an input voltage range of 1.8 V to 7 V. Key electrical parameters include a switching frequency of 500 kHz, an operating temperature range of -40°C to +85°C, and surface-mount installation. It is classified as a DC/DC converter within the PMIC category.
Feature Summary
- Integrates dual output channels for comprehensive power management
- Supports SEPIC topology for flexible input voltage handling
- Designed for operation with dual-cell battery configurations
Applications
- Dual-cell battery powered portable devices
- Power management for mobile communication modules
- Embedded systems requiring multiple regulated rails from a single source
Procurement Notes
Verify component status carefully as sources indicate discontinuation at certain distributors. Confirm package details match the 16-VQFN specification. Ensure compatibility with dual-cell input requirements. Check for updated datasheets reflecting current manufacturing status. Validate ordering information against official Texas Instruments documentation before purchase.
Selection Notes
Select this component when designing circuits requiring simultaneous regulation from dual-cell batteries. The integrated SEPIC and secondary regulator reduce external component count. Consider the 500 kHz switching frequency for size constraints. Verify thermal performance within the specified -40°C to +85°C range for the target application environment.
Part Context
This part belongs to the Texas Instruments TPS61132 series of power management ICs. It is distinct from the TPS61092 and TPS61030 boost converters which feature different topologies and output capabilities. The TPS61132 specifically addresses dual-output needs compared to single-output alternatives in the broader TPS61xx family.
Replacement Considerations
Public sources indicate the TPS61132RSAR may be discontinued at some distributors. No specific public substitute part numbers are confirmed in the provided data. Consult Texas Instruments directly for current availability or recommended replacements.
