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 margin
up/down controls, pre-bias start-up capability and efficiencies up to 94%. The
PTH03050
has an input voltage of
2.95V - 3.65V
and offers a wide
0.8V to 2.5V
output voltage range
with up to 6A output current, which allows for maximum design flexibility and a pathway
for future upgrades.
•6A output current
•3.3V input voltage
•Wide-output voltage adjust (0.8V to 2.5V)
•Auto-track™ sequencing*
•Margin up/down controls
•Pre-bias start-up capability
•Efficiencies up to 94%
•Output ON/OFF inhibit
•Output voltage sense
•Point-of-Load-Alliance (POLA) compatible

Notes
1Remote ON/OFF. Active High
ON: Pin 3 open; or V > Vin - 0.5V
OFF: Pin 3 GND; or V < 0.8V (min - 0.2V).
2See Figure 1 for safe operating curve.
3A 100µF electrolytic input capacitor is required for proper operation. The
capacitor must be rated for a minimum of 300mA rms of ripple current.
4An external output capacitor is not required for basic operation. Adding
100µF of distributed capacitance at the load will improve the transient
response.
51A/µs load step, 50 to 100% Iomax, Cout = 100µF.
6If utilized Vout will track applied voltage by ±0.3V (up to Vo set point).
7The pre-bias start-up feature is not compatible with Auto-
Track™. This is because when the module is under Auto-Track™
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™function must either be disabled, or the module’s
output held off using the Inhibit pin. Refer to Application Note
153 for more details.
8Tape and reel packaging only available on the surface-mount
versions.

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 0.8V to 2.5V. When the PTH03050 converter leaves the
factory the output has been adjusted to the default voltage of 0.8V
