these pins. When converting to a single channel buck-boost, all of the components on the VBL net must be
upgraded to 100V rating. It may also be necessary to upgrade Q1. Observe the schematic recommendations.
Addtionally, CREF1 may be changed to a 1uF 6.3V X5R (0402 minimum) ceramic capacitor when converting to a
one channel design. CREF1 must be 10uF 6.3V X5R (0603 minimum) for 2 FXS designs.
