4 / 12 page  AMC2596 Copyright © 2006 ADDtek Corp. 4 DD008_A -- JUNE 2006 RECOMMENDED OPERATING CONDITIONS Temperature Range -40°C≦TJ≦+125°C Supply Voltage 4.5V to 40V ELECTRICAL CHARACTERISTICS Unless otherwise specified, these specifications apply VIN = 12V, ILOAD = 0.5A and the operating ambient temperatures TJ = 25°C. Parameter Symbol Conditions Min Typ Max Units Output Voltage VOUT 4.75V ≤ VIN ≤ 40V, 0.2A ≤ ILOAD ≤ 3A 3.168 3.3 3.342 V Efficiency AMC2596-3.3 η VIN = 12V, ILOAD = 3A (Note 3) 73 % Output Voltage VOUT 7V ≤ VIN ≤ 40V, 0.2A ≤ ILOAD ≤ 3A 4.800 5.0 5.200 V Efficiency AMC2596-5.0 η VIN = 12V, ILOAD = 3A (Note 3) 80 % Feedback Voltage VFB 4.5V ≤ VIN ≤ 40V, 0.2A ≤ ILOAD ≤ 3A 1.193 1.230 1.267 V Efficiency AMC2596-ADJ η VIN = 12V, ILOAD = 3A (Note 3) 73 % Feedback Bias Current Ib Adjustable Version Only, VFB =1.3V 10 50 nA Oscillator Frequency fOSC (Note 4) 127 150 173 KHz Saturation Voltage VSAT IOUT = 3A (Note 5,6) 1.16 1.4 V Max Duty Cycle (ON) 100 Min Duty Cycle (OFF) DC (Note 8,9) 0 % Current Limit ILIMIT Peak Current (Note 5,6) 3.6 4.5 6.9 A Output = 0V (Note 5,7) 50 µA Output Leakage Current ILEAK Output = -1V (Note 8) 2 30 mA Quiescent Current IQ (Note 9) 5 10 mA Standby Current ISTBY ENABLE pin=5V (OFF) (Note 8) 80 200 µA VIH Low(Regulator ON) 0.6 V ENABLE Pin Threshold Voltage VIL High(Regulator OFF) 2.0 IH VLOGIC=2.5V(Regulator OFF) 5 15 µA ENABLE Pin Input Current IL VLOGIC=0.5V(Regulator OFF) 0.02 5 µA 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 100 pF capacitor discharged through a 1.5K resister into each pin. Note 3：External components such as the catch diode, inductor, input and output capacitors, and voltage programming resistors can affect switching regulator system performance. When the AMC2596 is used as shown in the Figure 1 test circuit, system performance will be as shown in system parameters section of Electrical Characteristics. Note 4：The switching frequency is reduced when the second stage current limit is activated. The amount of reduction is determined by the severity of current over-load. Note 5：No diode, inductor or capacitor connected to output pin. Note 6：Feedback pin removed from output and connected to 0V to force the output transistor switch ON. Note 7：Feedback pin removed from output and connected to 12V for the 3.3V, 5V, and the ADJ. version, and 15Vfor the 12V version, to force the output transistor switch OFF. Note 8：VIN＝40V |
