5. Application Circuit for M57161L-01
between pins 5 and 6 consists of the built-in optocoupler’s LED in series with a 390Ω resistor. This combination is
designed to provide approximately 10mA of drive current for the optocoupler when a control signal of 5V is
applied. If another control voltage is desired then an external current limiting resistor can be added. The value of
the external resistor can be calculated by assuming the forward voltage drop of the optocoupler’s photodiode is
2V. For example, if 15V drive is desired the required external resistor would be: (15V-2V)÷10mA - 390Ω = 910Ω.
The control power supply must be decoupled with a capacitor connected as close as possible to the driver’s pins.
This decoupling capacitor is included to provide a stable, well-filtered voltage for the primary side of the driver’s
built-in DC-DC converter. When selecting the input decoupling capacitor it is important to insure that it has a
