DESCRIPTION  
The TPS65320-Q1 power supply is a combination of a single high-voltage switch-mode asynchronous buck  
power supply and an LDO regulator. This is a monolithic high-voltage switching regulator with an integrated  
switch of 40 V, a power MOSFET, and a low-standby-current LDO. The device has a voltage supervisor which  
monitors the outputs of the switch-mode power supply. To reduce heat, the input supply of the LDO can auto-  
source from the input voltage to the output of the buck. The low-voltage tracking feature can possibly eliminate  
the need to use a boost converter during cold-crank conditions.  
The TPS65320-Q1 has a switching frequency range from 100 kHz to 2.5 MHz, providing customers with a  
flexible design to fit their system needs. The external loop compensations allow the user to optimize the  
converter response for the appropriate operating conditions. The standby current of the buck regulator is 140 µA  
for low-power mode.  
The device has built-in protection features such as soft start, pulse-by-pulse current limit, thermal sensing, and  
shutdown due to excessive power dissipation.
