2A, 32V, 330KHz Step-Down Converter
The Future of Analog IC Technology
DESCRIPTION
The MP1591 is a high voltage step-down converter ideal for automotive power adapter battery chargers. Its wide 6.5V to 32V input voltage range covers the automotive battery’s requirements and it achieves 2A continuous output for quick charge capability. Current mode operation provides fast transient response and eases loop stabilization. Fault protection includes cycle-by-cycle current limiting and thermal shutdown. In shutdown mode, the converter draws only 20A of supply current. The MP1591 requires a minimum number of readily available external components to complete a 2A step-down DC to DC converter solution.
