The AON6926 is designed to provide a high efficiency
synchronous buck power stage with optimal layout and
board space utilization. It includes two specialized
MOSFETs in a dual Power DFN5x6A package. The Q1
"High Side" MOSFET is desgined to minimze switching
losses. The Q2 "Low Side" MOSFET is an SRFET™ that
features low R
DS(ON)
to reduce conduction losses as well as
an integrated Schottky diode with low Q
RR
and V
f
to reduce
switching losses. The AON6926 is well suited for use in
compact DC/DC converter applications.

A. The value of R
θJA
is measured with the device mounted on 1in
2
FR-4 board with 2oz. Copper, in a still air environment with T
A
=25°C. The Power
dissipation P
DSM
is based on R
θJA
and the maximum allowed junction temperature of 150°C. The value in any given application depends on the
user's specific board design.
B. The power dissipation P
D
is based on T
J(MAX)
=150°C, using junction-to-case thermal resistance, and is more useful in setting the upper
dissipation limit for cases where additional heatsinking is used.
C. Repetitive rating, pulse width limited by junction temperature T
J(MAX)
=150°C. Ratings are based on low frequency and duty cycles to keep initial
T
J
=25°C.
D. The R
θJA
is the sum of the thermal impedence from junction to case R
θJC
and case to ambient.
E. The static characteristics in Figures 1 to 6 are obtained using <300 µs pulses, duty cycle 0.5% max.
F. These curves are based on the junction-to-case thermal impedence which is measured with the device mounted to a large heatsink, assuming a
maximum junction temperature of T
J(MAX)
=150°C. The SOA curve provides a single pulse rating.
G. The maximum current rating is limited by package.
H. These tests are performed with the device mounted on 1 in
2
FR-4 board with 2oz. Copper, in a still air environment with TA=25°C.
