MP1583 (U38)
DESCRIPTION
The MP1583 is a step-down regulator with abuilt-in internal Power MOSFET. It achieves 3A
of continuous output current over a wide input supply range with excellent load and line
regulation.
Current mode operation provides fast transient response and eases loop stabilization.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device
reliability. The absolute maximum ratings are stress ratings only.
