说明

• Typical Application for the L5972D device is a step-down monolithic power switching regulator capable of delivering up to 2 A at output voltages from 1.235 V to 35 V. The operating input voltage ranges from 4.4 V to 36 V. The device has been designed using BCDV technology and the power switching element is implemented through a P-channel DMOS transistor. It does not require a bootstrap capacitor, and the duty cycle can range up to 100%. An internal oscillator fixes the switching frequency at 250 kHz. This minimizes the LC output filter
