Description

Pin Configuration

The 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,

duringpower up and power down.

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 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.

Denotes negative logic:

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 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
