Typ. Max. ELECTRICAL CHARACTERISTICS (continued) SM60X SM60X APPLICATION CIRCUITS Note 4. In switching an inductive load, the current will lead the voltage on turn-on and lag the voltage on turn-off (see Figure 2). Therefore, Voltage Delay Time (t DV) ≅ tdi + tri and Current Storage Time (tsi) ≅ tsv + tfv . Note 5. The efficiency is a measure of internal power losses and is equal to Output Power divided by Input Power. The switching speed circuit of Figure 1, in which the efficiency measured, is represenative of typical operating conditions for the SM600 series switching regulators. Note 6. SM610/611/612 Test Circuit and waveforms are identical but of opposite polarity (V IN = -25V, V OUT = -5V, I DRIVE = +20mA).
