DESCRIPTIONThe PTH05050W is one of the smallest non-isolated power modules from Texas Instruments that featuresAuto-Track ™ sequencing. Auto-Track simplifies supply voltage sequencing in power systems by enablingmodules to track each other, or any other external voltage, during power up and power down.Although small in size (0.87 in × 0.5 in), these modules are rated for up to 6 A of output current, and are an idealchoice in applications where space, performance, and a power-up sequencing capability are important attributes.The product provides high-performance step-down conversion from a 5-V input bus voltage. The output voltageof the PTH05050W can be set to any voltage over the range, 0.8 V to 3.6 V, using single resistor.Other operating features include an on/off inhibit, output voltage adjust (trim), and output over-current protection.For high efficiency these parts employ a synchronous rectifier output stage, but a pre-bias hold-off capabilityensures that the output will not sink current during startup.Target applications include telecom, industrial, and general purpose circuits, including low-power dual-voltagesystems that use a DSP, microprocessor, ASIC, or FPGA.Package options include both throughhole and surface mount configurations.
