4 / 13 page AP1539 18V 4A 300KHz BUCK CONVERTER AP1539 Rev. 4 4 of 13 OCTOBER 2009 DS31477 www.diodes.com © Diodes Incorporated Absolute Maximum Ratings Symbol Parameter Rating Unit ESD HBM Human Body Model ESD Protection 5.5 KV ESD MM Machine Model ESD Protection 200 V VCC VCC Pin Voltage VSS - 0.3 to VSS + 20 V VFB Feedback Pin Voltage VSS - 0.3 to VCC V VEN EN Pin Voltage VSS - 0.3 to VCC V VOUT Switch Pin Voltage VSS - 0.3 to VCC V PD Power Dissipation Internally limited mW TJ Operating Junction Temperature Range -40 to +125 oC TST Storage Temperature Range -65 to +150 oC Caution: The absolute maximum ratings are rated values exceeding which the product could suffer physical damage. These values must therefore not be exceeded under any conditions. Recommended Operating Conditions Symbol Parameter Min Max Unit VIN Input Voltage (Note 4) 3.6 18 V IOUT Output Current 0 4 A TA Operating Ambient Temperature -20 +85 oC Notes: 4. For the operations in low input voltage, AP1539 can tolerate down to 3.6V but max output current loading will be less than 4A. For nominal applications in such low input voltage range, especially lower than 4V, a higher ROCSET with larger heat sink is recommended. |
