Exposure to such conditions may adversely impact product reliability and result in failures not covered by warranty. NOTES: 4. θJA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See Tech Brief TB379 for details. 5. For θJC, the “case temp” location is the center of the exposed metal pad on the package underside. Electrical Specifications TA = -40°C to +125°C, VIN = 3V to 36V, unless otherwise noted. Typical values are at TA = +25°C. Boldface limits apply over the junction temperature range, -40°C to +125°C PARAMETER SYMBOL TEST CONDITIONS MIN (Note 8) TYP MAX (Note 8) UNITS SUPPLY VOLTAGE VIN Voltage Range VIN 336 V VIN Quiescent Supply Current IQ VFB = 0.7V, SYNC = 0V, FS = VCC 80 µA VIN Shutdown Supply Current ISD EN = 0V, VIN=36V (Note 6) 2 4 µA VCC Voltage VCC VIN = 6V, IOUT = 0 to 10mA 4.5 5.1 5.7 V POWER-ON RESET VCC POR Threshold Rising Edge 2.75 2.95 V Falling Edge 2.35 2.6 V OSCILLATOR Nominal Switching Frequency FS FS = VCC 430 500 570 kHz Resistor from FS to GND = 340kΩ 240 300 360 kHz Resistor from FS to GND = 32.4kΩ 2000 kHz Minimum Off-Time tOFF VIN = 3V 150 ns Minimum On-Time tON (Note 9) 90 ns FS Voltage VFS FS = 100kΩ 0.39 0.4 0.41 V Synchronization Frequency SYNC 300 2000 kHz SYNC Pulse Width 100 ns ERROR AMPLIFIER Error Amplifier Transconductance Gain gm External Compensation 165 230 295 µA/V Internal Compensation 50 µA/V FB Leakage Current VFB = 0.6V 1 150 nA Current Sense Amplifier Gain RT 0.46 0.5 0.54 V/A FB Voltage TA = -40°C to +85°C 0.590 0.599 0.606 V TA = -40°C to +125°C 0.590 0.599 0.607 V |
