OM1575 OMH1575 Series
Catch Diode
If the output must be capable of a sustained short, the IF rating must be above 3A. The use of an ultra fast diode
with soft recovery characteristics or a Schottky will be adequate. The major impact on Schottky versus an ultra
fast is efficiency. Schottkys will provide approximately 4% to 5% improvement for output voltage below 12V,
whereas above 12V the difference will become less significant. Breakdown rating must be in excess of VIN for
margin.
Input Capacitor
The value shown will be adequate for most applications. Ripple voltage at the switching frequency is caused by
the input capacitor supplying load current during the on time of the power switch. The use of a low ESR
switching type capacitor will minimize ripple to an acceptable level.
Layout
Use short connections with a central point ground to prevent improper operation caused by stray inductance and
ground loops.
Output Capacitor
Ripple voltage on VOUT is directly related to the value of COUT and the internal resistance ESR of COUT. Output
noise can be lowered by increasing COUT or by selecting a capacitor with a lower ESR. ESR must be
approximately 0.07 or above to maintain stability, otherwise raise value of COUT.
The above fixed and adjustable voltage selections will be adequate for most applications for output currents from
150mA to 1.0A. Applications of VOUT below 5V or above 24V may require component adjustment for maximum
performance; please contact factory for application assistance.
