... An output capacitor is also required to filter the output voltage and is needed for loop stability. The capacitor should be located near the CM2596 using short PC board traces. Low ESR types capacitors are recommended for low output ripple voltage and good stability. Generally, low value or low voltage (less than 12V) electrolytic capacitors usually have higher ESR numbers. For example, the lower capacitor values (220uF – ...

... Inductor Selection The CM2596 can be used for either continuous or discontinuous modes of operation. Each mode has distinctively different operating characteristics, which can affect the regulator performance and requirements. With relatively heavy load currents, the circuit operates in the continuous mode (inductor current always flowing), but under light load conditions, the circuit will be forced to the discontinuous mode (inductor current falls to zero for a period of time) ...

... Heatsink and Thermal Consideration Although the CM2596 requires only a small heatsink for most cases, the following thermal consideration is important for all operation. With the package thermal resistances θJA and θJC, total power dissipation can be estimated as follows: ...
