typical photo diode consumption will be very much negligible in reverse bias, may be arround 2-3uA
im just want to use a dcdc for reverse biasing photodiode, if there is no minimum consumption will device keep output voltage off ? can you suggest a DCDC for such for almost no low load conditions ?

I have been discussing one device here , but not sure if it can be used : TPS55340: Can TPS55340 be used for biasing photo diodes requiring high voltage ? - Power management forum - Power management - TI E2E support forums
kindly suggest one
