14 CIRCUIT DESCRIPTION

The WPME-VDLM 171043601 power module is a DC-DC power supply including the switching regulator with integrated MOSFETs,controllerandcompensation,aswellastheshieldedinductorintegratedinonepackage. Thecontrolschemeis basedonacurrentmode(CM)regulationloop. The VOUT of the regulator is divided by the feedback resistor network RFBT and RFBB and fed into the FB pin. The error amplifier compares this signal with the internal 1V reference. The error signal is amplified and controls the on-time of a fixedfrequencypulsewidthgenerator. ThissignaldrivesthepowerMOSFETs. The current mode architecture features a constant frequency during load steps. Only the on-time is modulated. It is internallycompensatedandstablewithlowESRoutputcapacitorsandrequiresnoexternalcompensationnetwork.

The recommended value for RFBT is between 100kΩ to 1MΩ. For example, if RFBT = 100kΩ then the resistance value of the lower resistor in the feedback network is indicatedinthetablebelowforcommonoutputvoltages. Table13:171043601outputvoltageselection.

15.2 STEP 2 Select the Input Capacitor (CIN)

The energy at the input of the power module is stored in the input capacitor. MLCC (multi-layer ceramic capacitor) input capacitors (2x 10µF + 2x 22nF) are required externally to provide cycle-by-cycle switching current and to support load transients. The external input capacitor must be placed directly at the VIN pin. Attention must be paid to the voltage, frequency,temperaturederatingandthermalclassoftheselectedcapacitor. TwooftheWürthElektronik885012209073 MLCCs together with two of the Würth Elektronik 885012206091 MLCCs in parallel have been experimentally verified to work with this power module. To reduce the loop inductance of the input loop it is recommended to place the capacitors symmetricallyonbothsidesofthemodule. Pleasecheckthe DESIGNEXAMPLE sectiontoseetherecommendedlayout.

16 MODES OF OPERATION

Dependingontheloadcurrent,inputvoltageandoutputvoltage,the171043601moduleisinoneoffouroperationalmodes:

• FPWMatheavyloadwhenloadcurrentisabovehalfoftheinductorcurrentripple.
• PFM mode during light load operation: Auto transition to PFM operation when switching frequency is decreased at verylightload.
• Frequency foldback: At high input voltage and low output voltages, the switching frequency is reduced to maintain regulation.
• Dropoutmode: Whentheoutputvoltagedropsbelowthereferencevalue,forexamplewhenthereisinsufficientinput voltagetokeeptheoutputvoltageregulatedatthedesiredvalue.

16.1 PFM Operation

Under light load conditions, the power module uses two methods to maintain high efficiency: Peak current-limited discontinuousconductionandlightloadfrequencyreduction. Inpeakcurrent-limiteddiscontinuousconductionmode,the power module controls the peak inductor current while preventing the inductor current from becoming negative. This resultsinareductionintheeffectiveswitchingfrequency,helpingtoregulatetheoutputvoltageandimproveefficiencyat lightload. Inlightloadfrequencyoperation,theoutputfromtheerroramplifierismonitored. Whenitfallsbelowacertain threshold and an offset between the feedback and reference voltages is detected, the switching frequency is reduced, further enhancing the power module’s efficiency. Notably, these two modes operate independently without transitioning betweenthem.

16.2 Frequency Foldback Operation

The module continues to regulate output voltage even if the input-to-output voltage ratio requires an on-time less than theminimumon-timeofthechipwithagivenclocksetting. Thisisaccomplishedusingvalleycurrentcontrol. Atalltimes, the compensation circuit dictates both a maximum peak inductor current and a maximum valley inductor current. If for any reason, valley current is exceeded, the clock cycle is extended until valley current falls below that determined by the compensation circuit. If the converter is not operating in current limit, the maximum valley current is set above the peak inductorcurrent,preventingvalleycontrolfrombeingusedunlessthereisafailuretoregulateusingpeakcurrentonly. Ifthe input-to-outputvoltageratioistoohigh,eventhoughcurrentexceedsthepeakvaluedictatedbycompensation,thehigh- side device cannot be turned off quickly enough to regulate output voltage. As a result, the compensation circuit reduces bothpeakandvalleycurrent. Oncealowenoughcurrentisselectedbythecompensationcircuit,valleycurrentmatchesthat beingcommandedbythecompensationcircuit.

18 PROTECTION FEATURES

18.1 Overcurrent Protection (OCP) and Short Circuit Protection (SCP)

The MagI3C 171043601 power module implements a cycle-by-cycle current limit (see I OC_XS in ELECTRICAL SPECIFICATION), which is realized through the peak current mode control architecture of the power module. The peak currentofthehighsideswitchandthevalleycurrentofthelowsideswitcharebothmonitored. Additionally, limitingthe valley current during an overcurrent scenario reduces the thermal stresses generated inside of the power module by reducingthermscurrentvalue. By monitoring both switch currents the user can be confident that the power module will be well protected against overcurrent and short circuit scenarios even in the most extreme conditions of operation, such as very high or low duty cycles. Underverylowdutycycleconditions,thepeakcurrentcanexceedtheovercurrentpresetvalue. Whenthisoccurs, thelowsideswitchisturnedonuntilthecurrentdropsbelowthepresetvalleycurrentvalue. Thisbehaviormayresultin pulse skipping, temporarily decreasing the effective switching frequency in order to better protect the power module duringovercurrentscenarios. The inductor current exceeding the peak protection value will only take place if the minimum on-time stated in the ELECTRICAL SPECIFICATIONSis violated. Even in such a scenario, the power module will still be protected. Following the recommended switching frequencies stated inStep 4of theDESIGN FLOWwill always ensure the minimum on-time is maintained. Figure18:171043601overcurrentprotectioninductorcurrent.

18.2 Over Temperature Protection (OTP)

Thermal protection helps prevent catastrophic failures due to accidental device overheating. The junction temperature of theMagI3Cpowermoduleshouldnotbeallowedtoexceeditsmaximumratings. Thermalprotectionisimplementedbyan internalthermalshutdowncircuit,whichactivateswhenthejunctiontemperaturereaches168°C(typ.). Underthethermal shutdown condition both MOSFETs remain off, causing the output voltage to drop. When the junction temperature falls below158°C(typ.) theinternalsoftstartisreleased,V OUT risessmoothly,andnormaloperationresumes.

18.3 Soft-Start

18.4 Enable and Integrated/Adjustable UVLO

TheMagI3CpowermoduleisenabledbysettingtheENpinhigh. WhentheENvoltagereaches1.263Vthepowermodule begins switching and the internal soft-start regulates the output voltage rise until the desired output voltage is met, allowingnormaloperationtotakeplace. Thedeviceincorporatesaninternalinputundervoltagelockout(UVLO)toprotectfromunexpectedbehavioratinputvoltages belowtherecommendedvalues. ThethresholdsoftheinternalUVLOareindicatedinthe ELECTRICALSPECIFICATIONS. An additional UVLO threshold of the power module can be externally set by adding a resistor between VIN and EN and a second resistor between EN and GND. This voltage divider should be chosen so that the desired minimum input voltage correspondsto1.263VatEN.

18.5 External Clock Synchronization (Sync)

The 171043601 MagI3C power module allows synchronization of the power module’s switching frequency with an externalclocksourceasareference. Thisfeatureisbeneficialwhentheuserrequiressynchronizationtotheapplication´s clockfrequency,forinstancetobetteroptimizeperformancefactorssuchasEMIforaspecificapplication. To realize this feature it is recommended to use the AC coupling circuit shown in figure22. The capacitor (CSYNC) and resistor(RENB)actasahighpassfilter, withvaluesof1nFandbothresistors(R ENT), (RENB)inthe100k Ω-rangehavebeen verified experimentally. When the power module detects a voltage change at the EN/SYNC pin it uses the external frequency source instead of the internal oscillator to set the switching frequency. The external clock must be off before start-uptoallowproperstart-upsequencing. It is recommended to use the default switching frequency, through the resistor RFSW, closest to the external source frequency. ThevalueofR ENT iscalculatedtochoosetheUVLOvalueasexplainedinthe EnableandIntegrated/Adjustable UVLO section. The external clock source should be a square wave with peak-to-peak voltage of 3.3V or higher and no negativevoltageduringthedeadtime. Theminimumclocksignalholdtimefortheexternalclocksourceisspecifiedinthe ELECTRICALSPECIFICATIONS.ToensurethereisnonegativevoltageappliedattheEN/SYNCpinthesumoftheDCvoltage acrossRENB andtheinjectedACsyncsignalneedtobeconsidered. Inthegivenexamplefromthe DESIGNEXAMPLE section,anAC-coupledsquarewavesignalisappliedtotheEnablepinvia a capacitor-resistor (C-R) high-pass filter. The EN/SYNC pin must never experience a negative voltage. The coupled AC signalcanresultinnegativevoltagesdependingonthedutycycleofthesignal,asitisaddedtotheDCvoltagelevelatthe EN/SYNCpin. InCase1,usinga50%clockdutycycleresultsinanoffsetoftheDCvoltageacrossR ENB byhalfofthesync signal’speak-to-peakvoltage,whichis1.65V.Therefore,thevoltageV RENB mustbeatleast1.65V.GivenR ENT =1MΩ and RENB = 63.4kΩ, the input voltage VIN needs to be 27.67V or higher. In Case 2, using a 10% clock duty cycle results in an offsetofonly0.33V.Therefore,bycalculation(withoutconsideringtheUVLOsetting),theinputvoltageV IN couldbe5.53V orhighertoensurenonegativevoltageacrosstheEN/SYNCpin.
