3 / 6 page TS2596 3-6 2003/12 rev. D Electrical Characteristics (Continued) Vin = 12V, IL = 500mA, Ta = 25 oC unless otherwise specified. TS2596 Adjustable Feedback Voltage (Note 1) 0.2A ≤ IL ≤ 3A, 8V ≤ Vin ≤ 40V, Vout=5V (Figure 2) 0.96|Vo| 1.23 1.04|Vo| V Efficiency Vin=12V, Vout=5V, IL=3A -- 75 -- % All Output Voltage Version (Vin= 12V, IL = 500mA) Oscillator Frequency (Note 2) 127 150 173 kHz Quiescent Current (Note 3) -- 5 10 mA Standby Current ENABLE =5V -- 70 200 uA Saturation Voltage (Note 4) ILOAD=3A -- 1.2 1.5 V Feedback Bias Current VOUT=5V (Adj.

Refer to Application information for details. Note 2: The oscillator frequency reduces when the second stage current limit is activated. The amount of reduction is determined by the severity of current over load. Note 3: For these parameters, FB is removed from VOUT and connected to +12V to force the output transistor OFF. Note 4: VOUT pin sourcing current. No diode, inductor or capacitor connected to VOUT. Note 5: FB is removed from VOUT and connected to 0V. |
