LMR514x5/LMR514x5-Q1 Synchronous Buck Converters

Texas Instruments LMR514x5/LMR514x5-Q1 Synchronous Buck Converters can drive up to 2.5A or 3.5A load current. By implementing a 4V to 36V wide input range, the devices are ideal for a wide range of industrial applications requiring power conditioning from an unregulated source. The wide-VIN, easy-to-use synchronous buck converters offer a 200kHz to 1MHz adjustable switching frequency with an external resistor, which supplies the flexibility to optimize efficiency or external component size.
