All buck converters need capacitors on the input. Actually, in a perfect world, if the supply had zero output impedance and infinite current capacity and the tracks had zero resistance or inductance, ...
The BD9C301FJ-LB is a 4.5 V to 18 V input, 3 A synchronous buck switching regulator with integrated low-on-resistance power MOSFETs. Features such as under-voltage, overcurrent, short circuit and ...
