Description

Pin Configuration

over the range, 0.8 V to 3.6 V, using a

single resistor.

Pin Function

The PTH05050 is one of the smallest

non-isolated power modules from Texas

Instruments 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.

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.

The product provides high-performance

step-down conversion from a 5-V input

bus voltage. The output voltage of the

PTH05050W can be set to any voltage

Package options include both through-

hole and surface mount configurations.
