4 / 11 page © 2009 Fairchild Semiconductor Corporation www.fairchildsemi.com FAN5343 • Rev. 1.0.4 4 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 Voltage on VIN Pin –0.3 6.0 V VFB, VEN Voltage on FB and EN Pins –0.3 VIN + 0.3 V VSW Voltage on SW Pin –0.3 25 V VOUT Voltage on VOUT Pin –0.3 25 V ESD Electrostatic Discharge Protection Level Human Body Model per JESD22-A114 3.3 kV Charged Device Model per JESD22-C101 2.0 TJ Junction Temperature –40 +150 °C TSTG Storage Temperature –65 +150 °C TL Lead Soldering Temperature, 10 Seconds +260 °C 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 Conditions Min. Max. Units VIN VIN Supply Voltage 2.7 5.5 V VOUT VOUT Voltage (1) 6.2 24.0 V IOUT VOUT Load Current 500mW Maximum Output Power 5 25 mA TA Ambient Temperature –40 +85 °C TJ Junction Temperature –40 +125 °C Note: 1. Application should guarantee that minimum and maximum duty-cycle should fall between 20-85% to meet the specified range. Thermal Properties Junction-to-ambient thermal resistance is a function of application and board layout. This data is measured with four-layer 2s2p boards in accordance to JEDEC standard JESD51. Special attention must be paid not to exceed junction temperature TJ(max) at a given ambient temperate TA. Symbol Parameter Typical Units θJA Junction-to-Ambient Thermal Resistance 70 °C/W |
