Step-Down Converter with Low Dropout Voltage Regulator

Description

SPICE simulation with transient and average models of the TPS65320-Q1. This is a high voltage switch-mode asynchronous buck power supply with a low dropout voltage regulator (LDO). The switching frequency varies between 100 kHz to 2.5 MHz, the Input voltage from 3.6V to 40V. In this simulation the output is 5V and the load current reaches 3.2 Ampere.
