SIC631CD-T1-GE3

The Vishay Dale SIC631CD-T1-GE3 is an integrated power stage solution designed for synchronous buck applications, offering high current, high efficiency, and high power density. Packaged in Vishay's proprietary 5 mm x 5 mm MLP package (PowerPAK® MLP55-31L), this device enables voltage regulator designs to deliver up to 50 A continuous current per phase.

Utilizing Vishay's Gen IV TrenchFET technology, the internal power MOSFETs significantly reduce switching and conduction losses. The integrated MOSFET gate driver IC features high current driving capability, adaptive dead-time control, an integrated bootstrap Schottky diode, and zero current detection for improved light load efficiency. It is compatible with a wide range of PWM controllers and supports 5 V PWM logic with tri-state and hold-off.

Key features include operation up to 2 MHz, optimization for 19 V input stages, and support for PS4 mode for reduced power consumption in standby states. The device also includes under-voltage lockout for VCIN and a user-selectable diode emulation mode (ZCD_EN#) to enhance light load performance. The operating temperature range is -40°C to 150°C (TJ).

This integrated power stage is suitable for multi-phase VRDs in computing, graphics cards, and memory, as well as Intel IMVP-8 VRPower delivery for Skylake, Kabylake, and Apollo Lake platforms. It supports up to 24 V rail input DC/DC VR modules.
