SCT82A30 Description
The SCT82A30 is a 100V voltage mode control synchronous buck controller with line feed forward. 40ns minimum on-time of controlled high side MOSFET supports high conversion ratio, enabling the direct stepdown conversion from a 48V input to low-voltage rail reducing system plexity and solution cost. The device operates at nearly 100% duty cycle if needed during input voltage drops as low as 5.5V.
