Control Signal Characteristics: Per Table on Page 4. Enable_H: This input signal is used to enable the output of the converter when activated (active High). The signal is referenced to either the output side (-Sense) or GND. It has an internal pull-up resistor. To disable the converter requires an open collector logic signal to pull it down.

4 Bit Logic Signals: The state of the 4 bit control signals controls

the output voltage. Normally, the 4 bits are in a ‘low state’ and provide for a 2.5V output voltage. The output voltage may be programmed between 1.429 to 2.5V by setting appropriate logic bits ‘high’ through D0, D1, D2, and D3. Powergood_H: The Powergood signal is in a ‘high’ state when the output voltage is within +/- 7.5% of the output voltage programmed by the 4 logic bit inputs. O VPFault_H: This signal is in a ‘high’ state when the output voltage is greater than +/-15% of the output voltage programmed by the 4 bit logic inputs or exceeds the maximum operating temperature of the converter. This output is the open emitter of a transistor which pulls to +5V in the high state and is open in the low state. For driving logic, an appropriate pull down resistor from O VPFault_H to – Sense is required. The OVPFault_H is asserted high when OVPFault is activated. When driving an SCR to ‘crow- bar’ the input source from a Fault_H signal, use the circuit below: Application Notes Trim: T he output voltage may be lowered from the nominal programmed value by adding an external resistor from the TRIM pin (J1-10) to – Sense (J1-1). This is used to obtain output voltages between the programmed values. The maximum value the output may be trimmed is approximately –4.5% of Vprog. The resistor value may be calculated from the following formula: (3.49) (Vprog – Vtrim) Vtrim = Desired output voltage with Rext tied from TRIM pin to – SENSE. Vprog = Nominal programmed output voltage Notes: 1. Vtrim must be less than Vprog. 2. The trim pin does not change the OVP or Powergood_H trip points.
