Multi-Rail, Low Iq power reference design for wearable applications

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. 

Features

• 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

Parts Include:

CC2650  SimpleLink multi-standard 2.4 GHz ultra-low power wireless MCU
TPS62770  Tiny Single-chip Dual Solution with 360nA Iq Buck and up to 15V Boost in WCSP
