DescriptionThe ATH06T033 series is one of the smallest non-isolated power modules that features Auto-Track™. Auto-Track™ simplifies supply voltage sequencing 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 in * 0.5 in), 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 product ATH06T033 provides high-performance step-down conversion from a 3.3-V input bus voltage.
The output voltage of the ATH06T033 can be set to any voltage over the range, 0.8 V to 2.5 V, using a Rset = Required to set the output voltage to a value higher than 0.8 V. (See spec. table for values) Cin = Required 100 F Co1 = Optional 100 F capacitor Co2 = Optional 10 F ceramic capacitor for reduced output ripple. single resistor.
Other ATH06T033 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 capability ensures that the output will not sink current during startup.
Target applications include telecom, industrial, and general purpose circuits, including low-power dual-voltage systems that use a DSP, microprocessor, ASIC, or FPGA. ATH06T033 Package options include both throughhole and surface mount configurations.
