NEW Product
The PTH03020 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
95%. The PTH03020 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 22 A 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 PTH03020 Series
The ultra-wide output voltage trim range offers major advantages to users who
select the PTH03020. 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 PTH03020 converter
leaves the factory the output has been adjusted to the default voltage of 0.8 V.
Notes
1 Remote ON/OFF. Positive Logic
ON: Pin 3 open; or V > Vin - 0.5 V
OFF:
Pin 3 GND; or V < 0.8 V (min - 0.2 V)
2 See Figure 1 for safe operating curve.
3 A 1,000 µF electrolytic input capacitor is required for proper operation.
The capacitor must be rated for a minimum of 700 mA rms of ripple
current.
4 An external output capacitor is not required for basic operation. Adding
330 µF of distributed capacitance at the load will improve the transient
response.
5 1 A/µs load step, 50 to 100% Iomax, Cout = 330 µF.
6 If utilized Vout will track applied voltage by ±0.3 V (up to Vo set point).
7 The pre-bias start-up feature is not compatible with Auto-Track™. This is
because when the module is under Auto-Trackcontrol, 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-Trackfunction must either be disabled, or the
module’s output held off using the Inhibit pin. Refer to Application Note
151 for more details.
8 Tape and reel packaging only available on the surface-mount versions.
9 To order Pb-free (RoHS compatible) surface-mount parts replace the
mounting option ‘S’ with ‘Z’, e.g. PTH03020WAZ. To order Pb-free
(RoHS compatible) through-hole parts replace the mounting option ‘H’
with ‘D’, e.g. PTH03020WAD.
