FIGURE 16. SHUTDOWN BY EN (VIN = 12V, VOUT = 1.8V AT 12A,
600kHz, CCM)
FIGURE 17. SHUTDOWN BY EN (VIN = 12V, VOUT = 1.8V AT 0A,
600kHz, DCM)
Typical Performance Curves Circuit of Figure 2. Design table on page 2 shows the components value for different
output voltages. Plots are captured from ISL85012EVAL1Z boards. VIN = 12V, VOUT = 1.8V, FREQ = 600kHz, CCM, TJ = -40°C to +125°C unless otherwise
noted. Typical values are at TA = +25°C. (Continued)
