3 / 7 page TS2576 3-7 2003/12 rev. A All Output Voltage Version (Vin=12V for 5V, 3.3V and Adjustable version, Vin=25V for 12V version, IL = 500mA) Oscillator Frequency (Note 2) 47 52 58 kHz Quiescent Current (Note 3) -- 5 10 mA Standby Current ENABLE =5V -- 70 200 uA Saturation Voltage (Note 4) ILOAD=3A -- 1.4 1.8 V Feedback Bias Current VOUT=5V (Adj. Version only) -- 50 100 nA Duty Cycle (Note 5) Operating (ON) 93 98 -- % Current Limit (Note 2)(Note 4) 4.2 7.0 8.8 A VOUT=0V -- 0.3 2 Output Leakage Current (Note 3) VOUT=-1V -- 7.5 30 mA VIH (VOUT=0V) 2.2 1.4 -- ENABLE Threshold Voltage VIL(VOUT=Normal Output Voltage) -- 1.2 1.0 V IIH (ENABLE =5V) -- 12 30 ENABLE Input Current IIH (ENABLE =0V) -- 0 10 uA Note 1: External components such as the catch diode, inductor, input and output capacitors can affect switching regulator system performance. Refer to Application information for details. Note 2: The oscillator frequency reduces to approximately 11KHz in the event of fault conditions, such as output short or overload. And the regulated output voltage will drop approximately 40% from the nominal output voltage. This self-protection feature lowers the average power dissipation by lowering the minimum duty cycle from 5% down to approximately 2%. 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. |
