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.

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. 2/6 www.freescale.net.cn AO4260 60V N-Channel MOSFET TYPICAL ELECTRICAL AND THERMAL CHARACTERISTICS 120 100 10V VDS=5V 3.5V 100 4V 80 4.5V 80 ID(A) ID (A) 60 3V 60 125°C 40 40 20 20 25°C VGS=2.5V 0 0 0 1 2 3 4 1 5 8 2 2.5 3 3.5 4 Normalized On-Resistance 2 6 RDS(ON) (mΩ Ω) 1.5 VGS(Volts) Figure 2: Transfer Characteristics (Note E) VDS (Volts) Fig 1: On-Region Characteristics (Note E) VGS=4.5V 4 VGS=10V 2 1.8 VGS=10V ID=18A 1.6 17 5 2 VGS=4.5V10 1.4 1.2 ID=16A 1 0.8 0 0 5 0 10 15 20 25 30 ID (A) Figure 3: On-Resistance vs. Drain Current and Gate Voltage (Note E) 25 50 75 100 125 150 175 0 Temperature (°C) Figure 4: On-Resistance vs. Junction 18Temperature (Note E) 12 1.0E+02 ID=18A 1.0E+01 10 40 125°C 1.0E+00 IS (A) RDS(ON) (mΩ Ω) 8 6 4 125°C 1.0E-01 1.0E-02 1.0E-03 25°C 25°C 2 1.0E-04 0 1.0E-05 2 6 8 10 VGS (Volts) Figure 5: On-Resistance vs. Gate-Source Voltage (Note E) 3/6 4 0.0 0.2 0.4 0.6 0.8 1.0 1.2 VSD (Volts) Figure 6: Body-Diode Characteristics (Note E) www.freescale.net.cn AO4260 60V N-Channel MOSFET TYPICAL ELECTRICAL AND THERMAL CHARACTERISTICS 6000 10 VDS=30V ID=18A Ciss 5000 Capacitance (pF) VGS (Volts) 8 6 4 2 4000 3000 Coss 2000 1000 Crss 0 0 0 10 20 30 40 50 60 Qg (nC) Figure 7: Gate-Charge Characteristics 70 80 0 20 30 40 50 VDS (Volts) Figure 8: Capacitance Characteristics 60 1000.0 TA=25°C 100.0 TA=100°C RDS(ON) limited 100 TA=150°C TA=125°C 10 ID (Amps) IAR (A) Peak Avalanche Current 1000 10 10µs 10.0 100µs 1.0 1ms 10ms TJ(Max)=150°C TA=25°C 0.1 10s DC 0.0 1 1 0.01 10 100 1000 Time in avalanche, tA (µ µs) Figure 12: Single Pulse Avalanche capability (Note C) 0.1 1 10 VDS (Volts) 100 1000 Figure 10: Maximum Forward Biased Safe Operating Area (Note F) 10000 TA=25°C Power (W) 1000 100 10 1 0.00001 0.001 0.1 10 1000 Pulse Width (s) Figure 11: Single Pulse Power Rating Junction-to-Ambient (Note F) 4/6 www.freescale.net.cn AO4260 60V N-Channel MOSFET TYPICAL ELECTRICAL AND THERMAL CHARACTERISTICS Zθ JA Normalized Transient Thermal Resistance 10 D=Ton/T TJ,PK=TA+PDM.ZθJA.RθJA 1 In descending order D=0.5, 0.3, 0.1, 0.05, 0.02, 0.01, single pulse RθJA=75°C/W 0.1 PD 0.01 Single Pulse Ton T 0.001 0.00001 0.0001 0.001 0.01 0.1 1 10 100 1000 Pulse Width (s) Figure 12: Normalized Maximum Transient Thermal Impedance (Note F) 5/6 www.freescale.net.cn AO4260 60V N-Channel MOSFET Gate Charge Test Circuit & Waveform Vgs Qg 10V + + Vds VDC - Qgs Qgd VDC - DUT Vgs Ig Charge Resistive Switching Test Circuit & Waveforms RL Vds Vds 90% + Vdd DUT Vgs VDC - Rg 10% Vgs Vgs t d(on) tr t d(off) t on tf toff Unclamped Inductive Switching (UIS) Test Circuit & Waveforms L 2 E AR = 1/2 LIAR Vds BVDSS Vds Id + Vdd Vgs Vgs I AR VDC - Rg Id DUT Vgs Vgs Diode Recovery Test Circuit & Waveforms Q rr = - Idt Vds + DUT Vds Isd Vgs Ig 6/6 Vgs L Isd + Vdd t rr dI/dt I RM Vdd VDC - IF Vds www.freescale.net.cn
