High-Efficiency, Fast-Transient, 3A, 4.2V-20V Input
Synchronous Step-down Converter
The Future of Analog IC Technology
in a QFN12 (2x3mm) Package
The MP28248 is a fully-integrated, high-
efficiency, synchronous, step-down, switch
mode converter. It offers a very compact
solution that can achieve a 3A continuous
output current over a wide input supply range
with excellent load and line regulation. The
MP28248 operates at high efficiency over a
wide output-current load range.
Constant-On-Time control mode provides fast
transient response and eases loop stabilization.
Full protective features include short-circuit
protection, over-current protection, over-voltage
protection, under-voltage protection, and
The MP28248 requires a minimal number of
readily-available standard external components.
This device is available in a space-saving
2mmx3mm 12-pin QFN package.
