Hi, TI expert.
The customer has an inquiry about the SMPS topology and component recommendations to be applied to the power supply of the following specifications.
--------------------------------------------------------------------------------------
1) Input: 3-phase 4-wire single-phase standard (220V +-20%)
2) Output: 4 channels
DC 12V, 30W
DC 12V, 12W
DC 12V, 12W
DC 12V, 12W
3) Requirements
a) Input, output isolation, output 4-channel GND separation
b) Each output power overcurrent protection
c) Regulation output voltage within 3%
d) Products capable of initial IC operating voltage DC
e) IC with input control (enable pin)
f) Total efficiency over 81%
g) Operating temperature -25 degrees to 70 degrees
--------------------------------------------------------------------------------------
We would like to ask for recommendations on SMPS topologies and components suitable for the above conditions.
Thank you.
