Frequently Asked Questions
What output current and input voltage range does the TPS628682ARQYR support?
The TPS628682ARQYR delivers up to 4 A of continuous output current from an input voltage ranging from 2.4 V to 5.5 V, making it well-matched to single-cell lithium-ion batteries and 5 V USB power rails in portable consumer and IoT devices.
How does PWM current-mode control in TPS628682ARQYR improve transient response in dynamic load applications?
Current-mode PWM control samples the inductor current every switching cycle, enabling the TPS628682ARQYR to respond to rapid load current changes from milliamps to 4 A within microseconds, maintaining output voltage regulation tighter than many voltage-mode designs in applications like wireless radio burst transmission.
When is TPS628682ARQYR a better choice than TPS62840 for a battery-powered sensor design?
When the design requires up to 4 A peak load current rather than a smaller continuous rating, the TPS628682ARQYR is the preferred option; its 4 A capability and 2.4 V minimum input handle Li-ion cells down to near-discharge conditions across the 9-pin WQFN footprint without the output derating seen in lower-rated converters.
