CONTROL NODE (remote sense operation) INPUT Modulator control node input. Driven by external error amplifier in remote sense operation. A3, A4 VT (adaptive loop operation) INPUT VTM TM input for temperature compensation. Leave disconnected for remote sense operation. B1, B2 ENABLE BIDIR Enables power supply when allowed to float high. 5.0V during normal operation. B3, B4 VAUX OUTPUT 9.0V auxiliary bias voltage. C1, C2 TRIM INPUT Selects operating mode. Adjusts output voltage in adaptive loop operation. C3, C4 IFB (Remote Sense operation) INPUT Current sense input for current limit and overcurrent protection in remote sense operation. Leave disconnected for adaptive loop operation. D1, D2 NC n/a Do not connect this pin. D3, D4 SGND INPUT Signal ground, reference for analog controls. Kelvin connected internally to –IN and -OUT. E1, E2 NC n/a Do not connect this pin. E3, E4 REF (adaptive loop operation) OUTPUT Reference voltage for internal error amplifier in adaptive loop operation. REF_EN (remote sense operation) OUTPUT Powers and enables external control circuit voltage reference in remote sense operation. F1, F2 AL (adaptive loop operation) INPUT Adaptive loop gain control. Sets the magnitude of the adaptive loop load line in adaptive loop operation. Leave disconnected for remote sense operation. F3, F4 VC OUTPUT Bias voltage to power VTM module during startup G1,G2 +IN INPUT POWER Positive input power terminal G3,G4 +OUT OUTPUT POWER Positive output power terminal H1,H2 -IN INPUT POWER RETURN Negative input power terminal. Connected internally to –OUT. H3,H4 -OUT OUTPUT POWER RETURN Negative output power terminal. Connected internally to -IN.
