Hi All,
I want to design power supply for below specification.
Could you please share your thought ?
Input : 12V-13.5V
Output : 5V or 3.3V
Current : 100mA
Case 1 : Output 5V@100mA, Power Dissipation(max) = (13.5-5)*100mA = 850mW
Case2 : Output 3.3V@100mA, Power Dissipation(max) = (13.5-3.3)*100mA = 1.02W
So both case1 and case considering the cost factor which is the best option - Linear regulator (LDO) or Buck Converter ?
Do i need heatsink in case linear regulator design ? Not sure if LDO is available to dissipate 1W power.
Thanks !
