SiC641A - 55A IPS

Download the SiC641A datasheet PDF. This datasheet also covers the SiC641 variant, as both devices belong to the same 55a ips family and are provided as variant models within a single manufacturer datasheet.

Description

The SiC641 and SiC641A are high frequency integrated power stage optimized for synchronous buck applications to offer high current, high efficiency, and high power density performance with very low shutdown current.

Features

  • high current driving capability, adaptive dead-time control, an integrated bootstrap switch, and user selectable zero current detection to improve light load efficiency. The driver is also compatible with a wide range of PWM controllers, supports tri-state PWM, and 5 V and 3.3 V PWM logic. The device also supports PS4 mode to reduce power consumption when the system is in standby state. The SiC641 and SiC641A offer operating temperature monitoring, protection features, and warning flags that imp.
