The PTH12050 series is the smallestnon-isolated power modules from TexasInstruments that features Auto-Track™Sequencing. Auto-Track simplifies thesequencing of supply voltages in powersystems by enabling modules to track eachother, or any other external voltage, duringpower up and power down.Although small in size (0.87 in × 0.5 in),these modules are rated for up to 6 A ofoutput current, and are an ideal choice inapplicaTIons where space, performance,and a power-up sequencing capability areimportant attributes.The series operates from an inputvoltage of 12-V to provide step-downconversion to a wide range of output voltages.The output voltage of the W-suffixdevice may set to any voltage over theadjust range, 1.2 V to 5.5 V. The L-suffixdevice has an adjustment range of 0.8 Vto 1.8 V. The output voltage is set withinthe adjustment range using a single externalresistor.Other operaTIng features include anon/off inhibit, output voltage adjust (trim),and output over-current protecTIon. Forhigh efficiency these parts employ a synchronousrecTIfier output stage.Target applications include telecom,industrial, and general purpose circuits,including low-power dual-voltage systemsthat use a DSP, microprocessor, ASIC, orFPGA.
