SHENZHENFREESCALE AO4260

AO4260
60V N-Channel MOSFET
General Description
The AO4260 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 RDS(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 RθJA is measured with the device mounted on 1in2 FR-4 board with 2oz. Copper, in a still air environment with TA =25°C. The
value in any given application depends on the user's specific board design.
B. The power dissipation PD is based on TJ(MAX)=150°C, using ≤ 10s junction-to-ambient thermal resistance.
C. Repetitive rating, pulse width limited by junction temperature TJ(MAX)=150°C. Ratings are based on low frequency and duty cycles to keep
initialTJ=25°C.
D. The RθJA is the sum of the thermal impedance from junction to lead RθJL 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 1in2 FR-4 board with
2oz. Copper, assuming a maximum junction temperature of TJ(MAX)=150°C. The SOA curve provides a single pulse rating.
