PRM48AH480x200A00
Signal Speciï¬cations (cont.)
Specifications apply over all line and load conditions, TINT = 25ºC and output voltage from 20.0 V to 55.0 V, unless otherwise noted.
Boldface specifications apply over the temperature range of -40ºC < TINT < 125ºC (T-grade).
SGND: Signal Ground
⢠All control signals must be referenced to this pin, with the exception of VC
⢠SGND is internally connected to -IN and -OUT

TRIM
⢠TRIM is used to select operating mode and trim the output voltage in Adaptive Loop Operation
⢠Internal pullup to VCC_INT through 10 k⦠resistor
⢠When pulled below 0.45 V during power up, Remote Sense / Slave Operation is selected
⢠When allowed to pull up above 0.55 V during power up, Adaptive Loop Operation is selected
⢠Operating mode is detected during power up and cannot be changed unless input power is cycled
