DC/DC Converter
URB1D_LMD-10WR3 Series
Design Reference
1. Typical application
All the DC/DC converters of this series are tested according to the recommended circuit (see Fig. 2) before delivery.
If a further decrease of the input and output ripple is required, properly increase the input & output of additional capacitors Cin and Cout
or select capacitors of low equivalent impedance，and ensure the capacitance should be lower than the max. capacitive load of the
product.
