TI全英文资源：PMP10750 is a System optimized (CISPR 25 Class 5) 20W design for upstream converter used in ADAS system with all the required automotive protection.The design has various protections such as Load dump through TVS (ISO pulse testing), Reverse Voltage (Innovative Smart diode with very low Iq), Battery Disconnect Switch with OVP protection (PFET) and is EMI optimized to meet Conductive EMI limits of CISPR25 Class5.Input voltage range is between 4.5V to 30V with OVP at 20V and hence will operate in wide input voltage conditions. LM74610 is used for Battery reverse protection which utilizes a charge pump to drive an N-channel FET to provide a resistive path for the bypass current to flow. LM53603Q1 is used as front end DC/DC Buck converter which is 2.2MHz switching, Synchronous rectified Wide Vin Buck Converter which can take transient up to 42V.
