4 / 20 page 4 LTC1142/LTC1142L/LTC1142HV ELECTRICAL C C HARA TERISTICS The q denotes specifications which apply over the full operating temperature range. Note 1: TJ is calculated from the ambient temperature TA and power dissipation PD according to the following formula: LTC1142CG: TJ = TA + (PD × 95°C/ W) Note 2: This current is for one regulator block. Total supply current is the sum of Pins 10 and 24 currents. Dynamic supply current is higher due to the gate charge being delivered at the switching frequency. See the Applications Information section. Note 3: In applications where RSENSE is placed at ground potential, the off- time increases approximately 40%. Note 4: The LTC1142/LTC1142HV-ADJ/LTC1142HV/LTC1142L-ADJ are not tested and quality-assurance sampled at – 40 °C to 85°C. These specifications are guaranteed by design and/or correlation. Note 5: The LTC1142L-ADJ allows operation down to VIN = 3.5V.
