5v 2a boost from 3,7v
Hi,
Im designing a microcontroller application with MSP430. It will operate with Li-ion 3.7V battery. The circuit needs 3 voltage stages : 5V, 3V, 2.5V
I thought about LDO with 3.7V to 3V conversion (TPS79730) as main value and then two dc/dc converters 3V/5V and 3V/2.5V
The application must be ultra-low power and i need max 10mA.
Is this a good approach at all ? What do u suggest ?
Thanks in advance
