Using nRF51822 with a 3V coin cell

[Mahesh Venkitachalam]

Is there a recommended boost converter for using nRF51822 with a 3V coin cell? I'd appreciate a pointer to a schematic.

Thanks

You don't need boost converter for 3V power source. nRF51822 runs from 1.8V. From a 3V coin cell, you can even use the built-in buck (stepdown) converter to reduce the battery drain while the battery is fresh.

Because the step-down is a switched (buck) converter which has less power loss than the default LDO...
