Features: MP2499A 36V, 3A Max, High-Efficiency, Sy nchronous, Step-Down Converter with Out put Line Drop Compensation DESCRIPTION The MP2499A is a synchronous, rectifie d, stepdown, switch-mode converter with built-in power MOSFETs. The MP2499A of fers a very compact solution that achie ves a maximum of 3A of continuous outpu t current with built-in, output, line d rop compensation. The MP2499A uses sync hronous mode operation to achieve high efficiency over the output current load range. Current-mode operation provides fast transient response and eases loop stabilization. Full protection feature s include over-current protection (OCP) and thermal shutdown. The MP2499A requ ires a minimal number of readily availa ble, standard, external components and is available in a space-saving QFN-13 ( 2.5mmx3mm) package. TYPICAL APPLICATION FEATURES  Wide 5V to 36V Continuou s Operating Input Range  85mΩ/55m Low RDS(ON) Internal Power MOSFETs High-Efficiency Synchronous Mode Operation  Default 270kHz Switching .

MP2499A
36V, 3A Max, High-Efficiency,
Synchronous, Step-Down Converter
with Output Line Drop Compensation
DESCRIPTION
The MP2499A is a synchronous, rectified, step-
down, switch-mode converter with built-in
power MOSFETs. The MP2499A offers a very
compact solution that achieves a maximum of
3A of continuous output current with built-in,
output, line drop compensation.
The MP2499A uses synchronous mode
operation to achieve high efficiency over the
output current load range. Current-mode
operation provides fast transient response and
eases loop stabilization.
Full protection features include over-current
protection (OCP) and thermal shutdown.
The MP2499A requires a minimal number of
readily available, standard, external
components and is available in a space-saving
QFN-13 (2.5mmx3mm) package.
