6 / 48 page  LT8311 6 8311f For more information www.linear.com/LT8311 ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C, VIN = 12V, VINTVCC = 8V, PMODE = 5V, CCG = CFG = 100pF, unless otherwise noted. (Note 2) PARAMETER CONDITIONS MIN TYP MAX UNITS SYNC Mode (Tie PMODE to INTVCC) SYNC High Trip Voltage SYNC Ramp Up Hysteresis l 0.9 1.2 –2.4 1.5 V V SYNC Low Trip Voltage SYNC Ramp Down Hysteresis l –1.5 –1.2 2.4 –0.9 V V SYNC Minimum Pulse Width SYNC = 0V to ±2V Pulse SYNC = 0V to ±6V Pulse (Note 5) l 40 20 100 ns ns SYNC Input Current –3.5V < SYNC < 3.5V SYNC = ±10V (Note 6, 7) l 300 ±1 400 µA µA SYNC Propagation Delay To CG/FG Outputs SYNC Rising Edge (0V to 2V) to CG Rising Edge (Note 8) SYNC Rising Edge (0V to 6V) to CG Rising Edge (Notes 5, 8) SYNC Falling Edge (0V to 2V) to FG Rising Edge (Note 8) SYNC Falling Edge (0V to 6V) to FG Rising Edge (Notes 5, 8), CCG = CFG = 3.3nF l l 100 75 100 85 150 150 ns ns ns ns TIMER Timeout Frequency RTIMER = 41.2k RTIMER = 71.5k RTIMER = 221k l l l 425 255 80 505 300 100 585 345 120 kHz kHz kHz TIMER Short-Circuit Current TIMER = 0V l 40 60 µA Current Comparator Current Comparator Trip Threshold CSP Ramp Up, RCSP = RCSN = 0Ω l 48 62 72 mV CSP Ramp Up, RCSP = RCSN = 1.62kΩ (Note 5) 0 mV Current Comparator Blank Time in Preactive Mode From Rising CG Edge Until Blanking Ends (Note 5) 250 ns Current Comparator Blank Time in SYNC Mode From Rising CG Edge Until Blanking Ends 400 ns CSP Current at Low CSP Voltage CSP = 0V (Note 6) l 30 38 50 µA CSP Current at High CSP Voltage CSP = 150V (Note 7) l 200 500 µA CSN Current CSN = 0V (Note 6) l 0.1 1 µA Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: The LT8311 is tested under pulsed load conditions such that TJ ~ TA. The LT8311E is guaranteed to meet specifications from 0°C to 125°C junction temperature. Specifications over the –40°C to 125°C operating junction temperature are assured by design, characterization and correlation with statistical process controls. The LT8311I is guaranteed over the –40°C to 125°C operating junction temperature range. The LT8311H is guaranteed over the –40°C to 150°C operating junction temperature range, and the LT8311MP is guaranteed over the –55°C to 150°C operating junction temperature range. High junction temperatures degrade operating lifetimes; operating lifetime is derated for junction temperatures greater than 125°C. Note 3: The LT8311 includes overtemperature protection that is intended to protect the device during momentary overload conditions. Junction temperature will exceed the maximum operating junction temperature when overtemperature is active. Continuous operating above the specified maximum operating junction temperature may impair device reliability. Note 4: Rise and fall times of are measured between 10% and 90% points of a signal edge. Note 5: Guaranteed by design and/or correlation to static test. Note 6: Current flows out of pin. Note 7: Current flows into pin. Note 8: Propagation delay is measured between 50% point of the two signal edges of interest. Note 9: SS charge current refers to current flowing out of SS pin after certain conditions satisfied upon LT8311 wake-up (see the flowchart for Opto-Control Operation at Start-Up in Figure 9). Note 10: CSW is a square waveform (duty cycle = 50%) with VHIGH = 7V and VLOW = –0.7V. |
