12-VAC to 28-VAC: 7.5-W to 25-W ideal diode full-bridge rectifier reference design
Description
This reference design implements the LM74610-Q1 zero IQ reverse polarity protection smart diode controller to control the high-side rectifier MOSFETs for both line and neutral inputs of a 12-VAC to 28-VAC power supply. The design was tested at loads from 7.5 W to 25 W. The use of low Rdson MOSFETs with ideal diode drivers eliminates the high losses found in standard diode rectifiers. Applications are video doorbells and smart thermostats that run off of a home or building 12-V or 24-V AC transformer.
