4 / 45 page LM2598 SNVS125C – MARCH 1998 – REVISED APRIL 2013 www.ti.com LM2598-5.0 Electrical Characteristics Specifications with standard type face are for TJ = 25°C, and those with boldface type apply over full Operating Temperature Range. Symbol Parameter Conditions LM2598-5.0 Units (Limits) Typ Limit (1) (2) SYSTEM PARAMETERS (3) Test Circuit Figure 24 VOUT Output Voltage 7V ≤ VIN ≤ 40V, 0.1A ≤ ILOAD ≤ 1A 5 V 4.800/4.750 V(min) 5.200/5.250 V(max) η Efficiency VIN = 12V, ILOAD = 1A 82 % (1) Typical numbers are at 25°C and represent the most likely norm. (2) All limits specified at room temperature (standard type face) and at temperature extremes (bold type face). 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). (3) External components such as the catch diode, inductor, input and output capacitors can affect switching regulator system performance. When the LM2598 is used as shown in the Figure 24 test circuit, system performance will be as shown in system parameters of Electrical Characteristics section.
