Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: The LTC3872E is guaranteed to meet performance specifications from 0°C to 85°C junction temperature. Specifications over the –40°C to 85°C operating junction temperature range are assured by design, characterization and correlation with statistical process controls. PARAMETER CONDITIONS MIN TYP MAX UNITS Oscillator Frequency Normal Operation VFB = 1.2V 500 550 650 kHz Gate Drive Rise Time CLOAD = 3000pF 40 ns Gate Drive Fall Time CLOAD = 3000pF 40 ns Peak Current Sense Voltage IPRG = GND (Note 6) IPRG = Float IPRG = VIN ● ● ● 80 145 240 100 170 270 120 195 290 mV mV mV Default Internal Soft-Start Time 1ms The ● denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. VIN = 4.2V unless otherwise noted. (Note 2) ELECTRICAL CHARACTERISTICS Note 3: TJ is calculated from the ambient temperature TA and power dissipation PD according to the following formula: TJ = TA + (PD • 110°C/W) Note 4: The dynamic input supply current is higher due to power MOSFET gate charging (QG • fOSC). See Applications Information. Note 5: The LTC3872 is tested in a feedback loop which servos VFB to the reference voltage with the ITH pin forced to the midpoint of its voltage range (0.7V ≤ VITH ≤ 1.9V, midpoint = 1.3V). Note 6: Rise and fall times are measured at 10% and 90% levels. TYPICAL PERFOR A CE CHARACTERISTICS FB Voltage vs Temperature FB Voltage Line Regulation ITH Voltage vs RUN/SS Voltage TA = 25°C unless otherwise noted. |
