DCM4623xD2H26F0y7z  
Signal Specifications  
Specifications apply over all line, trim and load conditions, internal temperature TINT = 25ºC, unless otherwise noted. Boldface specifications apply over the  
temperature range of -40°C < TINT < 125°C for T grade and -55°C < TINT < 125°C for M grade.  
Enable: EN  
• The EN pin enables and disables the DCM converter; when held low the unit will be disabled.  
• The EN pin has an internal pull-up to VCC and is referenced to the -IN pin of the converter.

Trim: TR  
• The TR pin enables and disables trim functionality when VIN is initially applied to the DCM converter.  
When Vin first crosses VIN-UVLO+, the voltage on TR determines whether or not trim is active.  
• If TR is not floating at power up and has a voltage less than TR trim enable threshold, trim is active.  
• If trim is active, the TR pin provides dynamic trim control with at least 30Hz of -3dB control bandwidth over the output voltage of the DCM converter.  
• The TR pin has an internal pull-up to VCC and is referenced to the -IN pin of the converter.

Fault: FT  
• The FT pin is a Fault flag pin.  
• When the module is enabled and no fault is present, the FT pin does not have current drive capability.  
• Whenever the powertrain stops (due to a fault protection or disabling the module by pulling EN low), the FT pin output Vcc and provides current to drive  
an external ciruit.  
• When module starts up, the FT pin is pulled high to VCC during microcontroller initialization and will remain high until soft start process starts.
