Designing with the 2.5 A DC-DC converter L5973D

Introduction
The L5973D is a step-down monolithic power switching regulator capable of delivering up to
2.5 A at output voltages from 1.235 V to 35 V. The operating input voltage ranges from 4.4 V
to 36 V. It has been designed using BCDV technology and the power switching element is
implemented through a P-channel D-MOS transistor. It does not require a bootstrap
capacitor, and the duty cycle can range up to 100%. An internal oscillator fixes the s
