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
limiting and thermal shutdown. In shutdown
mode, the converter draws only 20μA of supply
current.
current
The MP1591 requires a minimum number of
readily available external components to
complete a 2A step-down DC to DC converter
solution.
