DC-DC Low Voltage Gate Driver

Overview

OptiMOS™ driver PX3517 and PX3519 - high speed drivers for dual power MOSFET

OptiMOS™ driver PX3517 and PX3519

The OptiMOS™ driver products PX3517 and PX3519 are high speed drivers, designed to drive a wide range of dual high side and low side n-channel power MOSFETs in applications such as computing and telecom point-of-load (PoL). 

Combining the new devices with Primarion™ family of digital multi-phase controller ICs or digital point-of-load controller ICs and Infineon N-channel MOSFETs, the new devices form a complete core-voltage regulator solution for advanced micro and graphic processors as well as point-of-load applications. 

To tailor the efficiency of the system based on the customer conditions and needs, the OptiMOS™ driver devices provide the capability of driving the high-side gate and low-side gate with a variable gate driving voltage ranging from 4.5V up to 8V.
