The Future of Analog IC Technology
DESCRIPTION
The EV0020 is the evaluation board for the
MP1591; 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. 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 20µA 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.
