When the LM2672 is used as shown in Figure 19 test circuits, system performance is as specified by the system parameters section of Electrical Characteristics. (2) All limits specified at room temperature and at temperature extremes. All room temperature limits are 100% production tested. All limits at temperature extremes are specified through correlation using standard Statistical Quality Control (SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL). (3) Typical numbers are at 25°C and represent the most likely norm. 7.5 Electrical Characteristics – 3.3 V TJ = 25°C (unless otherwise noted; see Figure 19) (1) PARAMETER TEST CONDITIONS MIN(2) TYP(3) MAX(2) UNIT VOUT Output voltage VIN = 8 V to 40 V, ILOAD = 20 mA to 1 A TJ = 25°C 3.251 3.3 3.35 V TJ = –40°C to 125°C 3.201 3.399 VIN = 6.5 V to 40 V, ILOAD = 20 mA to 500 mA TJ = 25°C 3.35 3.3 3.35 TJ = –40°C to 125°C 3.201 3.399 η Efficiency VIN = 12 V, ILOAD = 1 A 86% (1) External components such as the catch diode, inductor, input and output capacitors, and voltage programming resistors can affect switching regulator performance.
