3 / 24 page  3 LTC1775 Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be impaired. Note 2: TJ is calculated from the ambient temperature TA and power dissipation PD according to the following formula: LTC1775CGN/LTC1775IGN: TJ = TA + (PD • 130°C/W) LTC1775CS/LTC1775IS: TJ = TA + (PD • 110°C/W) Note 3: The LTC1775 is tested in a feedback loop that adjusts VOSENSE to achieve a specified error amplifier output voltage (ITH). Note 4: Typical in application circuit with EXTVCC tied to VOUT = 5V, IOUT = 0A and FCB = INTVCC. Dynamic supply current is higher due to the gate charge being delivered at the switching frequency. See Applications Information. Note 5: Minimum input supply voltage is 4.3V at – 40 °C for industrial grade parts. Note 6: Rise and fall times are measured at 10% to 90% levels. The q denotes specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. VIN = 15V unless otherwise noted.
