PMP10709 is a system optimized 50 W power designs for A13 Wireless Charger Transmitter used in automotive system. The design has various front end automotive protections such as Load dump through TVS (ISO pulse testing), Reverse Voltage (Through PFET’s body diode), Battery Disconnect Switch with OVP protection (PFET). PMP10709 is primarily four Switch synchronous Buck – Boost design, which supports wide Input voltage range (7V-20V) and delivers any output from 1V-10V based on DAC output of the A13 Wireless Charger. The DAC output changes from 1V to 3.3V which in turn changes the output voltage from 10V to 1V (on the fly) as needed by the algorithm of A13 wireless charger’s transmitter. This design utilizes best in Class Synchronous four Switch Buck Boost Controller LM5175. The design accepts an input voltage of 7Vin to 20Vin and provides the output of 1V- 10V@5 A. Output current never exceeds 5A to protect the charging Coil. The average current regulation loop of the IC at the output is used for this protection.
