I am looking for two isolated switching regulator designs:
First one:
With 48V in, I want a programmable output range of 19V to 29V at 8A
With 36V in, I want a programmable output range of 10V to 16V at 8A
Second one:
With 36V in, I want a programmable output range of -10V to -19V at 9A
With 24V in, I want a programmable output range of -4V to -10V at 9A
For both, I want >90% efficiency when the output power is near its maximum.
The programming could be digital or analog but need not be accurate (we measure the output voltage and can trim the programming accordingly).
Is there anybody out there who can do such designs readily or point me to existing products that would do the job?
