Diodes is aiming at non-isolated mains-powered IoT nodes with an ac-dc power chip that can deliver 60mA at 3.3V. AL17050 is a universal (85-265Vac) universal off-line buck converter with an integrated 500V 30Ω mosfet. Static consumption is 100μA, which my calculator tels me is 24mW at 240V. “The device automatically adjusts to low loads, so it ...
