Hello All,
Searching for a charge pump to boost a 5V to 15V. The source to the charge pump comes from a Buck converter with wide input range from 4.5V to 30V. The 15V powers a MOSFET driver driving 6 N-FETs. I have not calculated the current required.
The MAX1683 has a app note showing it can be used as a voltage tripler by adding two schottky diodes in series but the Iout is about 30mA. I wish to know if i can use the same configuration with another charge pump to get a higher Iout or is there a better way to get 15V from the 5V rail. Off the shelf ones have 5V to12V but are expensive.
