The AO4892 uses trench MOSFET technology that is
uniquely optimized to provide the most efficient high
frequency switching performance. Both conduction and
switching power losses are minimized due to an
extremely low combination of R
DS(ON)
, Ciss and Coss.
This device is ideal for boost converters and synchronous
rectifiers for consumer, telecom, industrial power supplies
and LED backlighting.

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
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 10s junction-to-ambient thermal resistance.
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
initialT
J
=25°C.
D. The R
θJA
is the sum of the thermal impedance from junction to lead R
θJL
and lead to ambient.
E. The static characteristics in Figures 1 to 6 are obtained using <300µs pulses, duty cycle 0.5% max.
F. These curves are based on the junction-to-ambient thermal impedance which is measured with the device mounted on 1in
2
FR-4 board with
2oz. Copper, assuming a maximum junction temperature of T
J(MAX)
=150°C. The SOA curve provides a single pulse rating.
