Specifications are for TJ = 25°C (unless otherwise noted)
|SYSTEM PARAMETERS(3) (see Figure 9-13 for test circuit)|
|VFB||Feedback voltage||4.5 V ≤ VIN ≤ 40 V, 0.2 A ≤ ILOAD ≤ 3 A||1.23||V|
|VOUT programmed for 3 V|
(see Figure 9-13 for test circuit)
|TJ = 25°C||1.193||1.267|
|–40°C ≤ TJ ≤ 125°C||1.18||1.28|
|η||Efficiency||VIN = 12 V, VOUT = 3 V, ILOAD = 3 A||73%|
(1) All room temperature limits are 100% production tested. All limits at temperature extremes are specified via correlation using standard Statistical Quality Control (SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL).
(2) Typical numbers are at 25°C and represent the most likely norm.
External components such as the catch diode, inductor, input and output capacitors can affect switching regulator system performance. When the LM2596 is used as shown in Figure 9-13
, system performance is shown in the test conditions column.
