Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductors system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore ( ), the underscore ( ) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore ( ). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild questions onsemi.com.

The FDMF8811 integrates a driver IC, two power MOSFETs and a bootstrap diode into a thermally enhanced, compact 6.0 mm x 7.5 mm PQFN package. The PQFN www.onsemi.com packaging ensures low package resistance improving the current handling capability and performance of the part. PACKAGE MARKING With an integrated approach, the complete switching power stage is PICTURE DIAGRAM optimized with regards to driver and MOSFET dynamic performance, system parasitic inductance, and Power MOSFET R . The DS(ON) DGWWAA TM FDMF8811 uses high performance PowerTrench MOSFET FDMF technology, which reduces switch ringing in converter applications. The 8811 driver IC features low delay time and matched PWM input propagation delays, which further enhance the performance of the part. 36 Lead PQFN Features D=Assembly Plant Code Compact size 6.0 mm x7.5 mm PQFN G= Year Code WW=Work Week High current handling: 20A AA= Lot Code >97% system efficiency at 600W full bridge applications PSRR FDMF8811= Specific Device Code value Pin Connections Wide driver power supply range: 8V to 14V Internal pull-down resistors for PWM inputs (HI,LI) 36 35 32 30 29 28 27 34 33 31 3.3V/TTL compatible input thresholds NC 1 Short PWM propagation delays 26 VIN HI 2 Drive power supply Under-voltage lockout (UVLO) 3 NC 37 LI PGND 4 Integrated 100V Half-Bridge gate driver with 1ohm Bootstrap diode 25 VIN PGND 5 Low Inductance and low resistance packaging for minimal operating VSS 6 p lower losses LO 7 24 VIN 100V PowerTrench MOSFETs for clean switching waveforms 8 VDD TOP VIEW LO 9 23 PGND Typical Applications PGND Telecom Half / full - Bridge DC-DC converters 10 Two-Switch Forward Converters PGND 11 22 PGND Intermediate Bus Converters 12 13 15 16 18 19 20 21 14 17 Brick Converters High-current DC-DC Point of Load (POL) converters.
