ORDERING INFORMATION Part Number Package Top Marking MP2497GN-A* SOIC8E MP2497-A * For Tape & Reel, add suffix –Z (e.g. MP2497GN-A–Z); PACKAGE REFERENCE SOIC8E ABSOLUTE MAXIMUM RATINGS (1) Input Voltage VIN .......................................... 60V VISN, VISP ..............................................0V to 25V |VISN -VISP| ...........................................0V to 0.4V VSW........................................-0.3V to VIN + 0.3V VBST ................................................... VSW + 6.5V All Other Pins...............................-0.3V to +6.5V Junction Temperature...............................150 C Lead Temperature ....................................260 C Storage Temperature............... -65 C to +150C Continuous Power Dissipation (TA = +25°C) (2) SOIC8E...................................................... 2.5W Recommended Operating Conditions (3) Input Voltage VIN ..............................4.5V to 50V Output Voltage VOUT (VIN>26.5V) .....0.8V to 25V Output Voltage VOUT (VIN<=26.5V) ...................... .........................................0.8V to (VIN–1.5)V Operating Junction Temp. (TJ). -40°C to +125°C Thermal Resistance (4) θJA θJC SOIC8E .................................. 50 ...... 10... C/W Notes: 1) Exceeding these ratings may damage the device. 2) The maximum allowable power dissipation is a function of the maximum junction temperature TJ (MAX), the junction-to- ambient thermal resistance θJA, and the ambient temperature TA. The maximum allowable continuous power dissipation at any ambient temperature is calculated by PD (MAX) = (TJ (MAX)-TA)/θJA. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. Internal thermal shutdown circuitry protects the device from permanent damage. 3) The device is not guaranteed to function outside of its operating conditions. 4) Measured on JESD51-7, 4-layer PCB. |
