CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. NOTES: 6. θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details. 7. θJA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. θJC, the “case temp” is measured at the center of the exposed metal pad on the package underside. See Tech Brief TB379. 8. All voltages are with respect to GND. Electrical Specifications Recommended operating conditions unless otherwise noted. Refer to Block Diagram and Typical Application schematic. VCC = +5.0V ±10%, TA = -40 to 85°C (Note 9), Typical values are at TA = 25°C PARAMETER TEST CONDITIONS MIN TYP MAX UNITS VCC SUPPLY Supply Voltage Range 4.5 5.0 5.5 V Shutdown Supply Current SHDN = GND - 55 100 µA Start-Up Current VCC < 3.7V - 0.1 0.20 mA Operating Supply Current (Note 10) - 3.7 6.0 mA REFERENCE VOLTAGE Output Voltage 1.237 1.25 1.262 V Long Term Stability TA = 125°C, 1000 hours - 5 - mV NEGATIVE FEEDBACK Source Current -1.0 2.0 mA CURRENT SENSE Maximum Input Signal 0.2 0.260 0.3 V Input Bias Current -2.0 0.0 2.0 µA Overcurrent Threshold 0.4 0.52 0.6 V ERROR AMPLIFIER Open Loop Voltage Gain -78- dB Gain-Bandwidth Product 10 - - MHz Input Voltage 1.225 1.25 1.275 V Input Bias Current -1.0 - µA PWM Maximum Duty Cycle 47 48 50 % Minimum Duty Cycle COMP = 0V - 0 - % UNDERVOLTAGE LOCKOUT Start Threshold 3.7 4.1 4.3 V Stop Threshold 3.2 3.6 4.0 V ISL6401 |
