Document number: DS37634 Rev. 5 - 2 9 of 11 www.diodes.com February 2020 © Diodes Incorporated DMC1028UFDB Typical Application Circuit DMC1028UFDB is designed for Point-of-Load (POL) converter that is stepping down from a nominal 3.3V to 1V with a load current up to 3A. This is implemented with a separate ASIC that is PWM signaling the complementary MOSFETs to act as a synchronous buck converter. T he control switch (Q2) is implemented with P-channel MOSFETs to avoid needing a charge pump and with the 3.3V to 1V step down, which has a duty cycle of 33%. This means that for 67% of the cycle, the synchronous switch (Q1) is on and efficiency is dominated by the conduction losses; hence, the need for low R DS(ON) N-channel MOSFETs. Whereas for the control switch (Q2) , the gate charge needs to be minimized as the switching losses become significant. 0.001 0.01 0.1 1E-05 0.0001 0.001 0.01 0.1 1 10 100 1000 r(t), TRANSIENT THERMAL RESISTANCE t1, PULSE DURATION TIME (sec) Figure 25 Transient Thermal Resistance RθJA(t)=r(t) * RθJA RθJA=166℃/W Duty Cycle, D=t1/t2D=Single Pulse D=0.005 D=0.01 D=0.02 D=0.05 D=0.1 D=0.3 D=0.5 D=0.7 D=0.9
