wpmdl110xxx1s / 17301xx78 magi 3 c power module fdsm ? fixed step down regulator module we-online.com wrth elektronik eisos gmbh & co. kg ? data sheet rev. 1.0 ? november 2015 8/12 block diagram circuit description the magi3c power module 173xxxx78 is based on a non-synchronous step-down regulator with integrated mosfet, free- wheeling diode, power inductor, input and output capacitors. the control scheme is based on a current mode (cm) regulation loop. the v out of the regulator is divided with the internal feedback resistor network and fed into the error amplifier which compares this signal with the internal 0.8v reference. the error signal is amplified and controls the on-time of a fixed frequency pulse width generator. this signal drives the power mosfet. the current mode architecture features a constant frequency during load steps. only the on-time is modulated. it is internally compensated and stable with low esr output capacitors and requires no external compensation network.
wpmdl110xxx1s / 17301xx78 magi 3 c power module fdsm ? fixed step down regulator module we-online.com wrth elektronik eisos gmbh & co. kg ? data sheet rev. 1.0 ? november 2015 9/12 protective features over temperature protection (otp) the junction temperature of the magi3c power module should not be allowed to exceed its maximum ratings. thermal protection is implemented by an internal thermal shutdown circuit which activates at 165c (typ.), causing the device to enter a low power standby state. in this state the mosfet remains off causing v out to fall. thermal protection helps to prevent catastrophic failures from accidental device overheating. when the junction temperature falls back below 165 v out rises smoothly and normal operation resumes. over current protection (ocp) for protection against load faults, the magi3c power module incorporates cycle-by-cycle current monitoring. during an overcurrent condition the output current is limited and the output voltage is reduced. when the overcurrent condition is removed, the output voltage returns to the nominal voltage. output overvoltage protection (ovp) when the output voltage goes above approx. 109% of the specified output voltage the high side mosfet will be forced off until the output voltage falls below approx. 107% of specified output value. short circuit protection (scp) the short circuit protection is realized via cycle by cycle current monitoring. recovery from short circuit protection mode occurs during the switching cycle following the removal of the short circuit condition.
