说明

  • Typical Application Circuit for LTM4642EY 4.5V to 20V Input, 650kHz, 0.9V and 1.2V Outputs at 4A Each. 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
