DESCRIPTION
The SiC413 is an integrated, dc-to-dc power conversion
solution with built-in PWM-optimized high- and low-side
n-channel MOSFETs and advanced PWM controller. The
SiC413 provides a quick and easy to use POL voltage
regulation solution for a wide range of applications. Vishay
Siliconix proprietary packaging technology is used to
optimize the power stage and minimize power losses
associated with parasitic impedances and switching delays.
The co-packaged Gen III TrenchFET power MOSFETs
deliver higher efficiency than lateral DMOS monolithic
solutions.
