All pins on a 2.54mm pitch and within ±0.25mm of true position. 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. |
