MP1591DN-LF-Z pressure converter imported original spot
MP1591DN-LF-Z
2A, 32V, 330KHz Buck Converter
Product Description
The MP1591 is a high voltage buck converter ideal for automotive power adapter battery chargers. Its wide input voltage range of 6.5 volts to 32 volts covers the requirements of car batteries and achieves a continuous output of 2A with fast charging capability. Current-mode operation provides fast transient response and simplifies loop stabilization. Fault protection includes cycle-by-cycle current limiting and thermal shutdown. In shutdown mode, the converter consumes only 20µA of supply current. The MP1591 requires a minimal number of off-the-shelf external components to complete a 2A step-down DC-DC converter solution
