Description

  • Typical Application Circuit for LTM4642IY 1MHz 4-Phase, Four Outputs (3.3V, 2.5V, 1.2V, 0.9V) with Tracking to the 3.3V Output. The LTM4642 is a complete dual 4A or single 8A step-down DC/DC regulator. Included in the package are the switching controller, power FETs, inductor and all support components. Operating over input voltage ranges of 4.5V to 20V, (2.375V min with external CPWR bias), the LTM4642 supports two outputs with voltage ranges of 0.6V to 5.5V, set by a single external resistor

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.
