Wearable applications like smart wristbands provide two main power rails to supply the wireless MCU, sensors, and the display. They are very tiny, and therefore require the smallest solution size possible. This reference design shows a full solution based on the TPS62770 multi-rail DC/DC converter, CC2650 wireless MCU, and a PMOLED display.
- Full adjustable Vout with TPS62770 dual output converter
- Single-chip wearable power supply
- Longer battery life due to ultra-low Iq
- Bluetooth® Smart interface for smartphone interaction
