3 / 29 page LM2592HV www.ti.com SNVS075C – MAY 2001 – REVISED APRIL 2013 ELECTRICAL CHARACTERISTICS LM2592HV-5.0 Specifications with standard type face are for TJ = 25°C, and those with boldface type apply over full Operating Temperature Range. Symbol Parameter Conditions LM2592HV-5.0 Units (Limits) Typ(1) Limit(2) SYSTEM PARAMETERS Test Circuit and Layout Guidelines(3) VOUT Output Voltage 7V ≤ VIN ≤ 60V, 0.2A ≤ ILOAD ≤ 2A 5 V 4.800/4.750 V(min) 5.200/5.250 V(max) η Efficiency VIN = 12V, ILOAD = 2A 81 % (1) Typical numbers are at 25°C and represent the most likely norm. (2) All limits ensured 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 ensured 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 LM2592HV is used as shown in the Test Circuit and Layout Guidelines, system performance will be as shown in system parameters section of Electrical Characteristics.
