Connect these pins either to open-drain outputs with or without external pull-up resistors or to active-pull-up outputs. VID0VID5 have 20uA internal pull-up current sources that diminish to zero as the voltage rises above 2.5V. These inputs can be pulled up as high as 5.3V. See note 2. Optional trim pin, used to adjust the output voltage. See note 1. VO-sen+ VO-sen- The open drain power good signal detects output under voltage only. It transitions to the high state after soft start has completed. If the output voltage falls below 74% of the nominal VID voltage, the signal is de-asserted. Remote voltage sense lines. Connect these at the point of load, to VO+ and VO- respectively. VO- Common return for both input and output VO+ Output voltage available to the load. OUTEN Logic level input used to enable the converter when high. VRM-pres Pin is tied to ground on module and is used by system to detect if a VRM is present. PWRGD 2004 Bel Fuse Inc.
