9.2.3 Application Curves

Figure 9-5 shows a test example of charging a 470-μF capacitor. Test conditions: VBB = 13.5 V, input is from low to high, load is a 470-µF capacitive load, ILIM pin is shorted to GND. CH4 is the output current. CH3 is the input step. CH2 is the output voltage, VOUT. CH1 is the supply voltage, VBB

Figure 9-6 shows a test example of a enable into short-circuit inrush current limit. Test conditions: VBB= 13.5 V, input is low to high, load is 5 µH + 100 mΩ, ILIM pin is shorted to GND. CH4 is the output current. CH3 is the input step. CH2 is the output voltage, VOUT. CH1 is the supply voltage, VBB

Figure 9-7 shows a test example of a load step from 500 mA to 3 A back to 500 mA. Test conditions: VBB= 13.5 V, input is high, load is 6.75 Ω and then changed to 4.5 Ω then back to 6.75 Ω, ILIM pin is shorted to GND. CH4 is the output current. CH3 is the SNS pin. CH2 is the output voltage, VOUT. CH1 is the supply voltage, VBB
