製品概要

概要

This 4-layer PCB demonstration board is designed as a step-down DC-DC converter to demonstrate the operation of the L6725 device in a general-purpose application. The input voltage can range from 4.5 V to 14 V with an output voltage of 3.3 V. The module can deliver an output current in excess of 20 A. The L6725 device can manage minimum ON times (TON) shorter than 100 ns. This makes possible conversions with very low duty cycles and very high switching frequencies. The switching frequency is initially set at 250 kHz (controller free-running FSW), but a switching frequency of 500 kHz can also be selected.
