Exposure to absolute maximum rating conditions for extended periods of time may affect reliability. VIN (XRP6124)............................................ -0.3V to 20V VIN (XRP6124HV)........................................ -0.3V to 32V GATE ...................................................... VIN-GATE<8V FB, EN ..................................................... -0.3V to 5.5V Storage Temperature .............................. -65°C to 150°C Power Dissipation ................................ Internally Limited Lead Temperature (Soldering, 10 sec) ................... 300°C ESD Rating (HBM - Human Body Model) .................... 2kV OPERATING RATINGS Input Voltage Range VIN (XRP6124)................3.0V to 18V Input Voltage Range VIN (XRP6124HV)............4.5V to 30V Junction Temperature Range ....................-40°C to 125°C Thermal Resistance θJA .....................................191°C/W ELECTRICAL SPECIFICATIONS Specifications are for an Operating Junction Temperature of TJ = 25°C only; limits applying over the full Operating Junction Temperature range are denoted by a “•”. Minimum and Maximum limits are guaranteed through test, design, or statistical correlation. Typical values represent the most likely parametric norm at TJ = 25°C, and are provided for reference purposes only. Unless otherwise indicated, VIN = 3.0V to 18V, TJ = –40°C to 125°C. Parameter Min.
