Overview
The TPS61100RGERG4 is a dual-output power management IC featuring one synchronous boost converter and one low-dropout regulator (LDO). It operates with an input voltage range of 2.7 V to 5.5 V. The boost channel provides up to 2 A output current, while the LDO supports up to 300 mA. Both outputs are adjustable. The device integrates a 500 kHz switching frequency and functions within a temperature range of -40°C to +85°C. It is housed in a 24-pin VFQFN package with an exposed pad.
Feature Summary
- Integrates a synchronous boost converter and a linear regulator for combined power solutions
- Supports high-efficiency step-up conversion with adjustable output voltages
- Includes integrated feedback resistors for simplified design
- Features thermal shutdown and overcurrent protection mechanisms
Applications
- Portable electronics requiring multiple voltage rails
- Mobile communication devices
- Handheld instrumentation
- Battery-powered systems
Procurement Notes
Verify the specific suffix 'RGERT' or 'RGERG4' against the datasheet to confirm package type and tape/reel specifications. Ensure the ordering part number matches the required RoHS compliance status and moisture sensitivity level. Cross-reference the manufacturer's latest documentation to confirm availability and any potential lifecycle changes before finalizing procurement.
Selection Notes
Select this component when a compact solution is needed for boosting battery voltage while simultaneously providing a stable LDO output. It is suitable for applications where space is limited due to the small 24-VFQFN package. Consider the total output current requirements and input voltage range to ensure the device operates within its specified efficiency curves and thermal limits.
Part Context
This part belongs to Texas Instruments' TPS611xx series of dual-output power management ICs. These devices are designed to replace separate boost and LDO regulators, reducing board space and component count. The series targets portable applications requiring efficient power conversion from single-cell lithium-ion batteries.
Replacement Considerations
Check for TPS61100 variants with different suffixes for package or reel options. Verify compatibility with TPS61101 if higher current is needed. Consult the TI replacement guide for pin-compatible alternatives.
