Description

This TI reference design is an automotive cluster wide Vin power supply solution that includes a wide Vin buck converter with an integrated LDO.   Also includes a highly efficient synchronous step-down, dc-dc converter. Along with a linear regulator designed to meet JEDEC SSTL-2 and JEDEC SSTL-18 specifications for DDR termination. This cluster power solution is optimized for the mid-end cluster market with the entire solution supporting 6.0V-40V system capabilities that can withstand start stop, and load dump conditions. The front end buck converter (TPS65320-Q1) is capable of supporting  4.5V  cold crank conditions.

Features
  • Wide input voltage range: 6.0V - 40V withstanding start/stop, and load dump conditions
  • Monolithic high-voltage switching regulator with an integrated switch of 40 V, a power MOSFET, and a low-standby-current LDO Switching frequency programmable 100kHz – 2.5MHz
  • 3-MHz 2-A Step-Down Converter in 2-mm x 2-mm SON Package
  • Sink/source voltage regulator that will provide the VTT termination voltage for DDR memory
