@blueroomelectronics:
I have to use a small display that fits in specific box (16x2 LCD 60mm wide max), if you can point me to a 3.3V display, I can use it
@Hero999:
It uses 2xAA batteries, TPS60120 generates 3.3V, TPS60140 generates 5V.
PIC has available ADC pin, and I am looking if someone already has design
PWM->inductror -> load-> feedback to ADC
@bananasiong:
this will be another option, but I need about 30mA, will it work? Can you point me to a working schematics please.
Like I said I have TPS60140 with 4 capacitors working, but trying to reduce cost.
