DC1723A

LTM8050 DC to DC Converter and Switching Regulator Chip 4.87VDC to 5.17VDC Output Demonstration Circuit

The demonstration board features LTM8050EY µModule regulator. The LTM8050EY is a 58VIN, 2A step down µModule converter. Included in the package are the switching controller, power switches, inductor and all support components. The DC1723A demonstration board is designed for a 5V, 2A output from a 7.5V to 58V input at 400KHz. The wide input range of the LTM8050EY allows a variety of input sources such as automotive batteries and industrial supplies. At light loads, the LTM8050EY enters burst mode operation to maintain high efficiency and low output ripple over a broad current range. The user adjustable features of the LTM8050 such as output voltage, switching frequency, soft start and power good can be changed on DC1723A simply by modifying or installing the appropriate resistors and/or capacitors.
