Power Module
(1) Place I / O external capacitors as near as possible to the connection pins. In particular make sure to minimize the
(2) Avoid frequent switching using the ON / OFF CTL pin (five times per second at the maximum).
(3) R1 and R2 resistors, which are used for changing the output voltage, are usually not required.
