MIC5353: Vin: 2.6V to 6V Vout: 1.25V to 5.1V Imax: 500mA Dropout (typical): 50mV@150mA, 160mV @ 500mA Accuracy: 2% initial Thermal shutdown and current limit Maximum output voltage is limited by the input voltage and the dropout voltage in the regulator. (Vmax = Vin - dropout) J100: - Cut-strap used for full separation of target power from the level shifters and on-board regulators. - For current measurements using the on-board power supply, this strap must be cut and an ammeter connected across. - For current measurements using an external power supply, this strap could be cut for more accurate measurements. Leakage back through the switch is in the micro ampere range.
Adjustable output and limitations: - The debugger can adjust the output voltage of the regulator between 1.25V and 5.1V to the target. - The level shifters have a minimal voltage level of 1.65V and will limit the minimum operating voltage allowed for the target to still allow communication. - The output switch has a minimal volatege level of 1.70V and will limit the minimum voltage delivered to the target. - Firmware configuration will limit the voltage range to be within the the target specification. - Firmware feedback loop will adjust the output voltage accuracy to within 0.5%.
