|MC44603DW from MOTO, Motorola 37pcs , SMD,MIXED FREQUENCY MODE GREENLINE PWM CONTROLLER|
|features consist of a foldback facility for overloadprotection, a standby mode when the converter output is slightly loaded, ademagnetization detection for reduced switching stresses on transistor anddiodes, and a high current totem pole output ideally suited for driving a power16MOSFET. It can also be used for driving a bipolar transistor in low power1converters (< 150 W). It is optimized to operate in discontinuous mode butP SUFFIXcan also operate in continuous mode. Its advanced design allows use inPLASTIC PACKAGEcurrent mode or voltage mode control applications.CASE 648Current or Voltage Mode Controller• Operation up to 250 kHz Output Switching Frequency16• Inherent Feed Forward Compensation• Latching PWM for Cycle–by–Cycle Current Limiting1• Oscillator with Precise Frequency ControlDW SUFFIXPLASTIC PACKAGEHigh FlexibilityCASE 751G(SOP–16L)• Externally Programmable Reference Current• Secondary or Primary Sensing• Synchronization FacilityPIN CONNECTIONS• High Current Totem Pole Output• Undervoltage Lockout with HysteresisV 1 16 RCC refSafety/Protection|
