MP2388
1A, 21V, 2MHz, High-Efficiency,
Synchronous, Step-Down Converter
in Ultra-Thin QFN Package
DESCRIPTION
The MP2388 is a high-frequency, synchronous,
rectified, step-down, switch-mode converter
with built-in, internal power MOSFETs. It offers
a very compact solution that achieves 1A 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.
Full protection features include over-current
protection (OCP) and thermal shutdown.
The MP2388 requires a minimum number of
readily available, standard, external
components and is available in a space-saving
QFN-8 (1.5mmx2.5mm) package.
FEATURES
Wide 4.5V to 21V Operating Input Range
1A Load Current
