These devices are intended for use in battery-powered NFC applications: the NFC radio’s performance is better when the analogue circuit can draw on a 5.0V supply.
The high efficiency of up to 94% offered by the PCA9410 and PCA9410A helps users to extend battery run-time by minimising power losses. Operating at a switching frequency of 3MHz, the converters can use a small inductor rated at 1μH or less.
- ±3% output-voltage accuracy over full current, voltage and temperature range
- Soft-start function limits in-rush current with true load disconnect
- Over-current and over-temperature protections
