9.6-14 VDC Input; 0.7525-5.5 VDC Programmable @ 20 A
Fig. 2.5V.4: Turn-on transient for Vout = 2.5 V with
application of Vin at full rated load current
(resistive) and 100 μF external capacitance at Vin =
12V. Top trace: Vin (10 V/div.); Bottom trace: output
voltage (1 V/div.); Time scale: 2 ms/div.
Fig. 2.5V.5: Output voltage ripple (20 mV/div.) at full
rated load current into a resistive load with external
capacitance 100 μF ceramic + 1 μF ceramic and Vin =
12 V for Vout = 2.5 V. Time scale: 2 μs/div.
Fig. 2.5V.6: Output voltage response for Vout = 2.5 V
to positive load current step change from 10 A to 20 A
with slew rate of 5A/μs at Vin = 12 V. Top trace:
output voltage (200 mV/div.); Bottom trace: load
current (5 A/div.). Co = 100 μF ceramic. Time scale:
20 μs/div.
Fig. 2.5V.7: Output voltage response for Vout = 2.5 V
to negative load current step change from 20 A to
10 A with slew rate of -5A/μs at Vin = 12 V. Top trace:
output voltage (200 mV/div.); Bottom trace: load
current (5 A/div.). Co = 100 μF ceramic. Time scale:
20 μs/div.
