PRM48BX480Y600A00 Datasheet, PDF (4/22 Pages) Vicor Corporation – High Efficiency Remote Sense PRM Converter

PRM48Bx480y600A00
Temperature Monitor
TM
• The TM pin monitors the internal temperature of the PRM analog control IC to within ±5 °C.
• Room temperature setpoint is ~ 3 V, approximate gain is 10 mV/°C.
• "Power Good" flag to verify that the PRM is operating
