SPECIFICATIONS
The PTH03050 is a next generation series of non-isolated dc-dc converters offering some
of the most advanced POL features available in the industry. The primary new feature
provides for sequencing between multiple modules, a function, which is becoming a
necessity for powering advanced silicon including DSP's, FPGA's and ASIC's requiring
controlled power-up and power-down. Other industry leading features include pre-bias
start-up capability and efficiencies up to 94%. The PTH03050 has an input voltage of
2.95 Vdc to 3.65 Vdc
and offers a wide 0.8 Vdc to 2.5 Vdc output voltage range with up to
6 A output current, which allows for maximum design flexibility and a pathway for future
upgrades.

A 100 F electrolytic input capacitor is required for proper operation. The
capacitor must be rated for a minimum of 300 mA rms of ripple current.
4
An external output capacitor is not required for basic operation. Adding
100 F of distributed capacitance at the load will improve the transient
response.

The pre-bias start-up feature is not compatible with Auto-Track
TM
. This is
because when the module is under Auto-Track
TM
control, it is fully active
and will sink current if the output voltage is below that of a back-feeding
source. Therefore to ensure a pre-bias hold-off, one of the following two
techniques must be followed when input power is first applied to the
module. The Auto-Track
TM
function must either be disabled, or the
module's output held off using the Inhibit pin. Refer to Application Note
153 for more details.

Tape and reel packaging only available on the surface-mount versions.

To order Pb-free (RoHS compatible) surface-mount parts replace the
mounting option `S' with `Z', e.g. PTH03050WAZ. To order Pb-free
(RoHS compatible) through-hole parts replace the mounting option `H'
with `D', e.g. PTH03050WAD.

The ultra-wide output voltage trim range offers major advantages to users who
select the PTH03050. It is no longer necessary to purchase a variety of
modules in order to cover different output voltages. The output voltage can be
trimmed in a range of 0.8 Vdc to 2.5 Vdc. When the PTH03050 converter
leaves the factory the output has been adjusted to the default voltage of 0.8 V.
