I have a device that someone has built for me for measuring amps/watts etc built to specific requirements that I have requested.
The main thing is that I want the unit to be self powered from the input (usually an ebike battery from 50-117v) so I need a component that will be as small as possible and will drop the voltage to circuit voltage (5V).
I have a super expensive ($8 a unit!) 10 leg component that does that up to 140V even but it keeps on burning whenever I go above 50V area, I guess I maybe exceed the max current draw of 400mA (I have a 1602 lcd with backlight on, gps module, ATmega328P mcu...).
The board is very small with mostly smd except for an Allegro current sensor and which is very big and I want to keep the unit as small as possible.
Any ideas?
