PTH03060
The PTH03060 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 93%. The
PTH03060 has an input voltage of
2.95V - 3.65V
and offers a wide 0.8V to 2.5V output
voltage range with up to 10A output current, which allows for maximum design flexibility
and a pathway for future upgrades.
All specifications are typical at nominal input, full load at 25°C unless otherwise stated

Output Voltage Adjustment of the PTH03060 Series
The ultra-wide output voltage trim range offers major advantages to users who
select the PTH03060. 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 PTH03060 converter leaves the
factory the output has been adjusted to the default voltage of 0.8V

OFF:
Pin 3 GND; or V < 0.8V (min - 0.2V).
See Figure 1 for safe operating curve.
A 330µF electrolytic input capacitor is required for proper operation. The
capacitor must be rated for a minimum of 700mA rms of ripple current.
An external output capacitor is not required for basic operation. Adding
330µF of distributed capacitance at the load will improve the transient
response.

The 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
154 for more details.
