3 / 13 page © 2009 Fairchild Semiconductor Corporation www.fairchildsemi.com FAN5353 • Rev. 1.0.2 3 Absolute Maximum Ratings Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Symbol Parameter Min. Max. Units VIN SW, PVIN, VCC Pins IC Not Switching -0.3 7.0 V IC Switching -0.3 6.5 Other Pins -0.3 VCC + 0.3 (3) V VINOV_SLEW Maximum Slew Rate of VIN Above 6.5V when PWM is Switching 15 V/ms RPGOOD Pull-Up Resistance from PGOOD to VCC 1 K Ω ESD Electrostatic Discharge Protection Level Human Body Model per JESD22-A114 2 KV Charged Device Model per JESD22-C101 2 KV TJ Junction Temperature –40 +150 °C TSTG Storage Temperature –65 +150 °C TL Lead Soldering Temperature, 10 Seconds +260 °C Note: 3. Lesser of 7V or VCC+0.3V. Recommended Operating Conditions The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not recommend exceeding them or designing to Absolute Maximum Ratings. Symbol Parameter Min. Typ. Max. Units VCC, VIN Supply Voltage Range 2.7 5.5 V VOUT Output Voltage Range 0.8 90% Duty Cycle V IOUT Output Current 0 3 A L Inductor 0.47 µH CIN Input Capacitor 10 µF COUT Output Capacitor 20 µF TA Operating Ambient Temperature -40 +85 °C TJ Operating Junction Temperature -40 +125 °C Thermal Properties Symbol Parameter Min. Typ. Max. Units θJA Junction-to-Ambient Thermal Resistance (4) 46 °C/W Note: 4. Junction-to-ambient thermal resistance is a function of application and board layout. This data is measured with four-layer 1s2p boards in accordance to JESD51- JEDEC standard. Special attention must be paid not to exceed junction temperature TJ(max) at a given ambient temperate TA. |
