TPS61120PWG4

Power Management - Specialized Overview

The TPS61120PWG4 is an adjustable boost converter integrated with a 200-mA low-dropout regulator (LDO), designed for single-cell lithium-ion or dual-cell battery applications. It operates within an input voltage range of 1.8 V to 5.5 V, featuring a nominal input of 3.3 V. The device utilizes pulse width modulation control in current-mode architecture to achieve high efficiency. Packaged in a 16-pin TSSOP, it supports operation across a temperature range of -40°C to 85°C and complies with RoHS standards.

• Optimized for single-cell lithium-ion and dual-cell battery powered systems
• Employs current-mode pulse width modulation control for stable regulation

Power Management - Specialized Applications

• Single-cell lithium-ion battery charging systems
• Dual-cell battery application power supplies
• Portable electronic devices requiring efficient step-up conversion

Power Management - Specialized Procurement Notes

Verify the specific package marking and date code against the manufacturer's latest datasheet to ensure authenticity. Confirm that the component meets the required environmental specifications for the intended operating temperature range. Cross-reference the ordering suffix with official Texas Instruments documentation to validate the exact variant and compliance status before finalizing procurement orders.

Power Management - Specialized Selection Notes

Select this component when designing circuits that require both high-efficiency voltage boosting and a regulated auxiliary supply from a single or dual cell source. The integrated LDO simplifies design by providing a stable output without additional external components. Ensure the application demands fit within the specified input voltage limits and thermal constraints of the TSSOP-16 package.

Power Management - Specialized Part Context

This part belongs to the TPS6112x family of power management ICs from Texas Instruments. These devices are engineered to provide efficient power solutions for portable electronics. The TPS61120 variant specifically offers adjustable output capabilities, distinguishing it from fixed-output counterparts like the TPS61121, which provides a fixed 3.3-V boost output.

Power Management - Specialized Replacement Considerations

The TPS61120PW is a direct functional equivalent regarding the core device type, differing primarily in the lead-free packaging suffix. Verify pin compatibility and electrical parameters against the TPS61121 if a fixed 3.3-V output is acceptable for the application.
