4 / 28 page  LT3743 4 3743f ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. VIN = 12V, VEN/UVLO = 5V, unless otherwise noted. PARAMETER CONDITIONS MIN TYP MAX UNITS PWMG Control Signals CTRL_SEL High to PWMGL Low Delay 10 40 ns CTRL_SEL High to PWMGH High Delay 150 200 ns CTRL_SEL Low to PWMGH Low Delay 30 60 ns CTRL_SEL Low to PWMGL High Delay 170 220 ns PWMGH and PWMGL Pull-up Impedance 3.2 Ω PWMGH and PWMGL Pull-Down Impedance 1.75 Ω Current Control Loop gm Amp Offset Voltage l –2.75 0 2.75 mV Input Common Mode Range VCM(LOW) VCM(HIGH) VCM(HIGH) Measured from VIN to VCM 0 2 V V Output Impedance 3.5 MΩ gm 375 475 625 μA/V Differential Gain 1.7 mV/V 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 LT3743 will function with a supply voltage as low as 4.5V, but to keep the gate drive voltages above 4V, the VCC_INT pin must be tied to VIN for operation below 6.0V Note 3: The LT3743E is guaranteed to meet performance specifications from 0°C to 125°C junction temperature. Specifications over the –40°C to 125°C operating junction temperature range are assured by design, characterization and correlation with statistical process controls. The LT3743I is guaranteed to meet performance specifications over the –40°C to 125°C operating junction temperature range. Note 4: The minimum on and off times are guaranteed by design and are not tested. |
