Description: | Dual Bootstrapped 12V MOSFET Driver |
Manufacturer: | Fairchild Semiconductor |
Datasheet: | PDF (696K). Click here to download *) |
The FAN5109B is a dual, high-frequency MOSFET driver, specifically designed to drive N-channel power MOSFETs in a synchronous-rectified buck converter. These drivers, combined with a Fairchild multi-phase pulse-width-modulated (PWM) controller and power MOSFETs, form a complete core voltage regulator solution for advanced microprocessors. The FAN5109B drives the upper and lower MOSFET gates of a synchronous buck regulator to 12VGS. The output drivers have the capacity to efficiently switch power MOSFETs at frequencies above 500KHz. The circuit's adaptive shoot-through protection prevents both MOSFETs from conducting simultaneously. The FAN5109B is rated for operation from 0C to +85C and is available in a low-cost SOIC-8 package. |
