Automotive digitally controlled boost power supply

This TI reference design is an automotive voltage boost converter module. The purpose of this module is to supply a steady voltage to vehicle electronics by boosting during voltage droop events such as engine crank. The design is based on the C2000 Real-Time Microcontroller, and will provide up to 400 Watts of power from a 12V automotive battery system.  This solution supports continuous operational input voltage of 6V-16V with protection against 36V load dump to provide a stable 12V output supply with reverse battery protection.

Features:
-Digitally controlled 3 phase Boost power topology implementation supporting up to 400W output power
-Digitally Controlled By-Pass Circuitry that Allows the  boost power supply to be bypassed during normal operation
-N-Channel MOSFET based reverse battery protection circuit reduces the power dissipation compared to a diode implementation
-Operational input voltage range of 6V to 16V with protection against 36V load dump
-Design can be used for engine start/stop applications

Parts Include:
INA195A-Q1 Automotive Grade, -16V to +80V, Low- or High-side, High-Speed, Voltage Output Current Shunt Monitor
LM4128-Q1 SOT-23 Precision Micropower Series Voltage Reference
LM5060-Q1 High-Side Protection Controller with Low Quiescent Current
