I need to design a power supply circuit for the following requirement:
1. 12V , 50mA
2. 5V , 200mA,
3. -5V , 50mA
7.5 V , 500mA is available as a source. I am looking for a single chip or double chip solution.
single chip :- all the required supplies will be generated by a single IC
Double chip- 5V and -5V will be generated by one IC and 12 V will be generated by the other IC.
Kindly give the possible IC part no.. If possible please provide the circuit diagram also.
Other solutions are also welcome.
Thank you !
With very best regards
