STEVAL-ISA025V1

Step-down DC-DC converter at 3.3 Vout/20 A and switching

frequency of 400 kHz evaluation board based on L6730

Features

Description

This 4-layer PCB demoboard implements a step-

down DC/DC converter and shows the operation

of the L6730 device in a general-purpose

application. The input voltage can range from

4.5 V to 14 V and the output voltage is 3.3 V. The

module can deliver an output current in excess of

30 A. The switching frequency is set at 400 kHz

(controller free-running FSW), but it can be

increased up to 1 MHz. A 7-position dip-switch

selects the UVLO threshold (5 V or 12 V bus), the

OVP intervention mode and the sink-mode current

capability.
