Features: The Future of Analog IC Technology MP22 29 High Efficiency 21V, 6A Synchronous Step-Down Converter with External Sync, Low-Power Mode, and External Soft-Star t DESCRIPTION The MP2229 is a high-fre quency, synchronous, rectified, step-do wn, switch-mode converter with internal power MOSFETs. It offers a compact sol ution to achieve a 6A continuous output current over a wide input-supply range with excellent load and line regulatio n. The MP2229 has synchronous-mode oper ation for higher efficiency over the ou tput current load range. Current-mode o peration provides fast transient respon se and eases loop stabilization. Full p rotection features include over-current protection (OCP) and thermal shutdown (TSD). The MP2229 requires a minimal nu mber of readily available, standard, ex ternal components and is available in a space-saving 3mm x 3mm 14-pin QFN pack age. TYPICAL APPLICATION FEATURES • Wide 4.5V to 21V Operating Input Range • 6A Output Current • Low 40mΩ/18mΩ RDS(ON) of Internal Power MOS.

The Future of Analog IC Technology
MP2229
High Efficiency 21V, 6A
Synchronous Step-Down Converter with External
Sync, Low-Power Mode, and External Soft-Start
DESCRIPTION
The MP2229 is a high-frequency, synchronous,
rectified, step-down, switch-mode converter
with internal power MOSFETs. It offers a
compact solution to achieve a 6A continuous
output current over a wide input-supply range
with excellent load and line regulation. The
MP2229 has synchronous-mode operation for
higher 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 (TSD).
The MP2229 requires a minimal number of
readily available, standard, external
components and is available in a space-saving
3mm x 3mm 14-pin QFN package.
