The Future of Analog IC Technology
The MP1498 is a high-f requency, synchronous,
rectified, st ep-down, switch-mode converter
with built-in internal power MOSFETs. It offers a
very compact solution to achieve 2A continuous
output curr ent with e xcellent loa d and line
regulation o ver a wide input supply range. The
MP1498 ha s synchronous mode operation fo r
higher efficiency over t he output current load
Current-mode operation provides a fa
transient response and eases loop stabilization.
Protective features include
protection, t hermal shutdown, and external SS
The MP149 8 requires a minimal number of
readily-available external compone nts and is
available in a space-saving 8-pin TSOT23
