Auto-Track simplifies the sequencing of supply voltages in power systems by enabling modules to track each other, or any other external voltage, during power up and power down. Although small in size (0.87 inches × 0.5 inches), these modules are rated for up to 6 A of output current, and are an ideal choice in applications where space, performance, and a power-up sequencing capability are important attributes. The series operates from an input voltage of 12-V to provide step-down conversion to a wide range of output voltages. The output voltage of the W-suffix device may set to any voltage over the adjust range, 1.2 V to 5.5 V. The L-suffix device has an adjustment range of 0.8 V to 1.8 V. The output voltage is set within the adjustment range using a single external resistor. Other operating features include an on/off inhibit, output voltage adjust (trim), and output overcurrent protection. For high efficiency, these parts employ a synchronous rectifier output stage. Target applications include tele, industrial, and general purpose circuits, including low-power dual-voltage systems that use the TMS320™ DSP family, microprocessor, ASIC, or FPGA.
