    Products Detail

    The LM2743-19A Demo Board is a synchronous buck converter solution targeting fixed and mobile telecommunications, industrial electronics, and distributed power markets. It features an input voltage range of 8V to 14V and adjustable output voltage from 1.2V to 3.3V at 19A with a fixed 300kHz switching frequency. The board implements current limit protection by sensing the voltage across the low-side MOSFET, eliminating the need for a current limit resistor in the power path. It includes adjustable soft-start, tracking functionality, remote ON/OFF, and power good signal. The PCB design uses four layers (top/bottom: 2oz copper, inner: 1oz copper) on FR4 laminate with compact dimensions of 56mm × 26.2mm × 10.3mm.

    Key Features

    • Space saving footprint, Wide ambient temperature range: -40°C to 65°C, Input voltage range: 8V to 14V, Adjustable output voltage: 1.2V to 3.3V, No minimum load requirement, Remote ON/OFF, Power good signal, Fixed switching frequency: 300kHz, Current Limit Protection, Master power supply start-up tracking function, Adjustable soft-start

    Application scenarios

    • fixed and mobile telecommunications
    • industrial electronics
    • distributed power
