(16)Do not use Pre-bias startup and sequencing together. If you do not use the track function, leave the seq/trk pin open. (17)After short circuit shutdown, if the load is partially removed such that the load still exceeds the overcurrent (OC) detection, the converter will remain in hiccup restart mode. (18)Output current limiting is disabled at start up to avoid overcurrent shutdown while charging external bypass capacitors. Output Adjustments Voltage Reference, The LSM2-T/30-D12 series includes a special output voltage trimming fea- ture which is fully compatible with competitive units. The output voltage may be varied using a single trim resistor from the Trim Input to Power Common. Use a precision, low-tempco resistor (±100 ppm/οC) mounted close to Figure 2. Voltage Trim Connections the converter with short leads. Be aware that the voltage accuracy is ±1.5% (typical) therefore adjust this resistance to achieve your desired output. Voltage Trim The LSM2 Series may also be trimmed using an external low-noise voltage applied between the Trim input and Output Common. Be aware that the inter- nal “load” impedance looking into Trim pin is below 1000 Ohms and includes factors from the output voltage. Therefore, use a low impedance source resistance in your external voltage reference. The fixed trim voltages to set the output voltage are: Vout (typ.) 0.80V. 1.0V. 1.2V. 1.5V. 1.8V.
