Description
Demonstration circuits 2297A-A and 2297A-B feature the LT®8570 and LT8570-1 in a boost configuration. These demo circuits demonstrate small size and low component count. Both converters are designed to convert a 5V to 10V source to 12V. Refer to Figures 3 and 4 for maximum load current at different input voltage levels.
Both converters use only one feedback resistor to set the output voltage.
The LT8570 can operate with inputs as high as 40V but in these demo circuits, the input is limited by the voltage rating of the input capacitors, and the magnitude of the output voltage.
The LT8570 and LT8570-1 include many other features such as synchronization to external clock, user configurable undervoltage lockout, soft-start, frequency foldback, and other features that are easily configured as Boost, SEPIC or Inverting Converters.
The data sheet gives a complete description of the device, operation and application information. The data sheet must be read in conjunction with this demo manual for DC2297A.
