5 / 32 page  5 LT1103/LT1105 ELECTRICAL CHARACTERISTICS SYMBOL PARAMETER CONDITONS MIN TYP MAX UNIT Switch Output Low Level ISW = 200mA q 0.25 0.50 V (LT1105) ISW = 750mA q 0.75 1.50 V Rise Time (LT1105) CL = 1000pF 50 ns Fall Time (LT1105) CL = 1000pF 20 ns ILIM Threshold Voltage (LT1105) Duty Cycle = 25% (Note 5) q 300 375 450 mV Low Switch Drive Lockout Measured at VSW (LT1103) q 9.0 9.5 10.5 V Threshold Measured at 15V Gate Bias Reference (LT1105) High Switch Drive Lockout Measured at VSW (LT1103) q 17.0 18.5 20.0 V Threshold Measured at 15V Gate Bias Reference (LT1105) The q denotes specifications which apply over the full operating temperature range. Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be impaired. Note 2: The OVLO pin is clamped with a 5.5V Zener and can sink a maximum input current of 1mA. Note 3: FB input bias current changes as a function of the VC pin voltage. Rate of change of FB input bias current is 11 µA/V of change on VC. By including a resistor in series with the FB pin, load regulation can be set to zero. Note 4: Current limit on VSW is constant for DC < 35% and decreases for DC > 35% due to internal slope compensation circuity. The LT1103 switch current limit is given by ILIM = 1.76 (1.536 – DC) above 35% duty cycle. Note 5: The current limit threshold voltage is constant for DC < 35% and decreases for DC > 35% due to internal slope compensation circuitry. The LT1105 switch current limit threshold voltage is given by VLIM = 0.225 (1.7 – DC) above 35% duty cycle.
