Application example
(1) When increasing the output voltage
(to negative voltage side)
(2) When reducing the output voltage
(near to zero voltage)

Operation notes
(1) Place I/O external capacitors as near as possible to the connection pins. In particular, make sure to
minimize the impedance between the input-side capacitor (C1) and pin 9. (Reference value: A length less
than 50mm is recommended for a copper foil of 1.0mm wide and 35µm thick.)
(2) Avoid frequent switching using the ON / OFF CTL pin (5 times per second at the maximum).
