Ultra-thin Open Frame Switching Regulator K78-JT-500R3-2

MORNSUN® Temperature Coefficient Notes: * 1. The "parallel cable" method is used for Ripple and Noise test, please refer to DC-DC Converter Application Notes for specific information; 2. With light loads at or below 20%, Ripple & Noise for 3.3V output parts increases to 100mVp-p max, and a load below 10% for 5V/9V/12V/15V output parts levels increase to 150mVp-p max.

Ultra-thin Open Frame Switching Regulator K78-JT-500R3-3

DC/DC ConverterK78 JT-500R3 Series Design Reference 1. Typical application 1. The required C1 and C2 capacitors must be connected as close as possible to the terminals of the module; 2. Refer to Table 1 for C1 and C2 capacitor values. For certain applications, increased values and/or tantalum or low ESR electrolytic capacitors may also be used instead; 3. Converter cannot be used for hot swap and with output in parallel; 4. To further reduce the output ripple and noise, we suggested the use of a “LC" filter at the output terminals, with an inductor value (L) of 10jH-47jH. MORNSUN GUANGZHOU SCIENCE...
