Frequently Asked Questions
What input voltage range does the RP400N501A-TR-FE support for battery-powered designs?
The RP400N501A-TR-FE operates over an input voltage range of 0.8V to 5.5V, with a nominal input of 1.5V, making it ideal for single-cell alkaline, NiMH, or lithium battery applications requiring step-up conversion to higher system voltages.
How does the RP400N501A-TR-FE achieve high efficiency across different load levels?
The converter automatically switches between PWM mode at heavy loads and VFM (variable frequency modulation) mode at light loads, optimizing efficiency across the full 0 to 0.8A output current range and extending battery life in duty-cycled IoT and wearable designs.
What package does the RP400N501A-TR-FE use, and how does it benefit compact PCB layouts?
It is housed in a SOT-23-5 (R-PDSO-G5) 5-pin small-outline package, one of the most compact industry-standard form factors for DC-DC converters, enabling PCB footprints under 3mm x 3mm and simplifying placement in space-constrained portable device designs.
