MPQ4425A
High Efficiency 1.5A, 36V, 2.2MHz,
Synchronous Step-Down LED Driver,
AEC-Q100 Qualified
DESCRIPTION
The MPQ4425A is a high-frequency,
synchronous, rectified, step-down, switch-mode
white LED driver with built-in power MOSFETs.
It offers a very compact solution to achieve 1.5A
of continuous output current with excellent load
and line regulation over a wide input supply
range. The MPQ4425A has synchronous mode
operation to get high efficiency.
Current mode operation provides fast transient
response and eases loop stabilization. Full
protection features include over-current
protection (OCP) and thermal shutdown (TSD).
The MPQ4425A requires a minimal number of
readily available, standard external components,
and is available in a space-saving QFN-13
(2.5mmx3mm) package.
