I'm looking to design a DCDC for APD biasing. DCDC requirement as following:
Vout = 35V
Vin = 3.3+/-5%
Iload = Max 20mA
Key concerning area: Smallest PCBA solution and efficiency at least >85%
I've look into below parts: LM3530, TPS61161A and TPS61165. Can i know which is the smallest PCBA solution? Is there any recommendation on PCBA layout?
