GENERAL DESCRIPTION:
The MSN12AD20-MQ is a high frequency, high
power density and complete DC/DC power
module. The PWM controller, power MOSFETs
and most of support components are integrated
in one hybrid package.
The features of MSN12AD20-MQ include
constant-on-time (COT) control mode that
provides fast transient response and eases loop
stabilization, programmable soft-start time,
protections, pre-biased output function and
output voltage tracking by external signal.
Besides, MSN12AD20-MQ is an easy to use
DC/DC power module, it only needs
input/output capacitors and one voltage dividing
resistor and one over current protection resistor
to perform properly.
The low profile and compact size enables
utilization of space on the bottom or top of PC
boards either for highly density point of load
regulation to save the space and area. It is
suitable for automated assembly by standard
surface mount equipment and complies with
Pb-free and RoHS compliance.

ELECTRICAL SPECIFICATIONS:
CAUTION: Do not operate at or near absolute maximum rating listed for extended periods of time. This stress may
adversely impact product reliability and result in failures outside of warranty.
NOTES:
1. Rth(jchoke-a) is measured with the component mounted on an effective thermal conductivity test board on 0 LFM
condition. The test board size is 80mm× 80mm× 1.6mm with 4 layers, 2oz per layer. The test condition is complied
with JEDEC EIJ/JESD 51 Standards.
