DCM3623X36G53C2YZZ Datasheet, PDF (8/25 Pages) Vicor Corporation – Isolated, Regulated DC Converter

DCM3623x36G53C2yzz
Signal Specifications
Specifications apply over all line, trim and load conditions, internal temperature T_INT = 25ºC, unless otherwise noted. Boldface specifications apply over the
temperature range of -40°C < T_INT < 125°C for T grade and -55°C < T_INT < 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 V_IN is initially applied to the DCM converter.
When Vin first crosses V_IN-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 V_CC 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 V_CC during microcontroller initialization and will remain high until soft start process starts.
