Description

  • DC2121A, Demonstration circuit 2121A features the LTM4634 a high efficiency, triple 5A/5A/4A step-down power module regulator. The input voltage range is from 4.75V to 28V. The output voltage range is 0.8V to 5.5V for Channel 1 and Channel 2, 0.8V to 13.5V for Channel 3. Derating is necessary for certain VIN, VOUT, frequency and thermal conditions. The DC2121A offers access to the TK/SS pins allowing the user to program output tracking or soft-start period. The board operates in continuous conduction mode in heavy load conditions

High Output Power Capability of Vishay’s SIC46X Family

In systems requiring step-down conversion from a high voltage of 24 V to 48 V bus at high power, a 60 V controller paired with discrete 80 V MOSFETs are typically used, especially when power levels exceed the 20 W range. This is mainly because even the best BCD processes cannot offer high performance MOSFETs in the 60 V to 80 V range.
