Features

  • enable a driver to operate in Boundary Conduction Mode (BCM) with valley switching where the average current in the inductor is the output current. The SSL2109 turns off the MOSFET when the voltage on pin SOURCE reaches 500 mV. If the value of R4 in parallel with R5 is 1, the peak current is limited to 500 mA. See Equation 1 0.5   R5 + R4  I peak = -------------------------------------R5  R4 (1) When the MOSFET is turned off, inductor L2 is discharged and the current flowing through the ind.
