CTRL (PIN 3)

Provides an on/off function. The converter

is on when CTRL is not connected or high

impedance (Z). The CTRL pin will turn the

converter off as indicated in general

characteristics.

CS (PIN 8)

Additional capacitance, up to 100uF can be

added from CS to pin 7. A low ESR

capacitor if fitted will precede the output filter

inductor and will improve ripple and noise.
