Buck converter The power losses associated with the FETs in a synchronous buck converter can be estimated using the equations shown in the table below. The formulas give a good approximation, for the sake of performance comparison, of how different pairs of devices affect the converter efficiency. However a very important parameter, the wotking temperature, is not considered. The real device behavior is really dependent on how the heat generated inside the devices is removed to allow for a safer working junction temperature. The low side (SW2) device requires: ● ● ● ● ● Very low RDS(on) to reduce conduction losses Small Qgls to reduce the gate charge losses Small Coss to reduce losses due to output capacitance Small Qrr to reduce losses on SW1 during its turn-on The Cgd/Cgs ratio lower than Vth/Vgg ratio especially with low drain to source voltage to avoid the cross conduction phenomenon. Small Rg and Lg to allow higher gate current peak and to limit the voltage feedback on the gate Small Qg to have a faster commutation and to reduce gate charge losses Low RDS(on) to reduce the conduction losses The high side (SW1) device requires: ● ● ● 9/16 Power losses estimation STD70N03L - STD70N03L-1 High side switch (SW1) Low side switch (SW2) Pconduction R DS ( on ) • I L • δ 2 R DS ( on ) • I L • ( 1 – δ) 2 Pswitching IL V in • ( Q gsth ( SW1 ) + Q gd ( SW1 ) ) • f • --Ig Zero voltage switching Recovery Pdiode Conduction Not applicable 1 Vin • Q rr ( SW2 ) • f Not applicable V f ( SW2 ) • I L • t deadtime • f Pgate(Qg) Q g ( SW1 ) • V gg • f Q gls ( SW2 ) • V gg • f PQoss V in • Q oss ( SW1 ) • f ------------------------------------------------2 V in • Q oss ( SW2 ) • f ------------------------------------------------2 Parameter d Qgsth Qgls Pconduction Pswitching Pdiode Pgate PQoss Duty-cycle Post threshold gate charge Third quadrant gate charge On state losses On-off transition losses Meaning Conduction and reverse recovery diode losses Gate driver losses Output capacitance losses 10/16 STD70N03L - STD70N03L-1 Package mechanical data 4 Package mechanical data In order to meet environmental requirements, ST offers these devices in ECOPACK® packages.
