Descripción

Traducción por IA

The ML4894 synchronous buck controller has been designed to provide high efficiency DC/DC conversion for portable products. The ML4894 can deliver a fixed 5V output from input voltages of 5.9V to 15V. The ML4894 drives external P- and N-channel MOSFETs in a synchronous buck topology, allowing an overall conversion efficiency of greater than 90% over an output current range exceeding three decades, with an output current capability of up to 5A. The regulator can be disabled via the SHDN pin. While disabled, the output of the regulator is completely isolated from the circuit’s input supply, and the supply current is reduced to less than 5μA to help extend battery life. The ML4894 converts a 5.9V to 15V input to a fixed 5V output using a unique current mode PFM synchronous buck control architecture. The output current is set by external components, and can exceed 2A. Even at light loads, the PFM architecture maintains high conversion efficiencies over a wide range of input voltages. If it is necessary to further extend battery life, the user can shutdown and fully disconnect the load from the input when the supply is not in use.
