Frequently Asked Questions
What input voltage range does the TPS61120PWRG4 support?
The TPS61120PWRG4 accepts input voltages from 1.8 V to 5.5 V at a nominal 3.3 V operating point. This range covers single-cell lithium-ion batteries (2.7 V to 4.2 V), dual-AA alkaline packs, and standard 3.3 V system rails, making it versatile for a broad range of portable power supply designs.
What are the dual output voltage and current ratings of the TPS61120PWRG4?
It provides a main output adjustable from 2.5 V to 5.5 V at up to 1.1 A, and an auxiliary output adjustable from 0.9 V to 5.5 V at up to 0.2 A. The dual-output architecture allows powering two independent load rails from a single converter, reducing total component count in space-constrained portable devices.
What control method does the TPS61120PWRG4 use?
It uses current-mode pulse width modulation (PWM) control, which provides inherent cycle-by-cycle current limiting for short-circuit protection and enables simpler loop compensation. Current-mode control also improves transient response compared to voltage-mode converters, which is important for loads with rapidly changing current demands.
Is the TPS61120PWRG4 RoHS compliant?
Yes. The JESD-609 code e4 and the G4 suffix in the part number confirm that the TPS61120PWRG4 is lead-free, halogen-free, and fully RoHS compliant. It meets Texas Instruments' green product requirements and is suitable for use in consumer electronics and industrial products sold in global markets with strict environmental regulations.
