I want to design a DC power supply for my Intel NUC small form factor PC using a battery.
The data-sheet for the PC:
There are internal power supply connectors and external DC jack. Both support only 19V.
I have a LiFePO4 battery that can supply
12 volts (at 10A max continuous discharge)
The input required for the PC is
19V drawing upto 3.42A
I am thinking of connecting a DC-DC step-up module at the battery output and supply the output to PC. The characteristics of the step-up module from its data sheet:
Input voltage : DC 10 - 32 V Output Voltage : DC 12-35 V(Adjustable) Output Current : 6A(MAX) Input current : 10A (MAX) (more than 10A please strengthen heatsink) Output Power : 100W (MAX) Conversion efficiency : 94% (when Input 19V 2.5A Output 16V, Reference) Output ripple : 2% (MAX) Working Temperature : industrial (- 40 ° c to +85 °c) ( environmental temperature, more than 40 degrees, please reduce power to use, or - enhance cooling). Full-Load temperature : 45 degrees No-load current : 25mA typical Voltage regulation : ± 0.5% Load regulation : ± 0.5% Dynamic response speed : 200us 5%
Will the step-up-module's output ripple affect the PC? How can I reduce the ripple if it is a problem?
