4 / 12 page CYStech Electronics Corp. Spec. No. : C548F5 Issued Date : 2007.12.11 Revised Date : Page No. : 4/12 LM2596-XXE5/F5 CYStek Product Specification Electrical Characteristics (Continued) Specifications with boldface type are for full operating temperature range, the other type are for TJ=25°C. Part No. Parameter Symbol Conditions Min Typ (Note 3) Max (Note 4) Units Output Voltage VOUT 4.75V≤VIN≤40V, 0.2A≤ILOAD≤3A 3.168 3.135 3.3 3.432 3.465 V LM2596-3.3 Efficiency η VIN=12V, ILOAD=3A - 73 - % Output Voltage VOUT 7V≤VIN≤40V, 0.2A≤ILOAD≤3A 4.800 4.750 5.0 5.200 5.250 V LM2596-5.0 Efficiency η VIN=12V, ILOAD=3A - 80 - % Output Voltage VOUT 15V≤VIN≤40V, 0.2A≤ILOAD≤3A 11.52 11.40 12.0 12.48 12.60 V LM2596-12 Efficiency η VIN=25V, ILOAD=3A - 90 - % Output Feedback VFB 4.5V≤VIN≤40V, 0.2A≤ILOAD≤3A VOUT programmed for 3V 1.180 1.168 1.230 1.280 1.292 V LM2596-ADJ Efficiency η VIN=12V, VOUT=3V, ILOAD=3A - 77 - % Note 1 : Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. Note 2 : The human body model is a 100pF capacitor discharged through a 1.5K resistor into each pin. Note 3 : Typical numbers are at 25℃ and represent the most likely norm. Note 4 : All limits guaranteed at room temperature (standard face type) and at temperature extremes(bold face type). All room temperature limits are 100% production tested. All limits at temperature extremes are guaranteed via correlation using standard Statistical Quality Control (SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL). Note 5 : External components such as the catch diode, inductor, input and output capacitors, and voltage programming resistors can affect switching regulator system performance. Note 6 : The switching frequency is reduced when the second stage current limit is activated. Note 7 : No diode, inductor or capacitor connected to output pin. Note 8 : Feedback pin removed from output and connected to 0V to force the output transistor switch ON. Note 9 : Feedback pin removed from output and connected to +12V for the 3.3V, 5V and adjustable version, and +15V for the 12V version, to force the output transistor switch OFF. Note 10 : VIN=40V. Note 11 : Junction to Ambient thermal resistance. (With copper area of approximately 3 in²) |
