| 3.3 Vin single output DC-DC CONVERTERS * * * * * * * * * * * POLA Non-isolated NEW Product 1 22 A output current 3.3 V input voltage Wide-output voltage adjust (0.8 Vdc to 2.5 Vdc) Auto-trackTM sequencing* Margin up/down controls Pre-bias start-up capability Efficiencies up to 95% Output ON/OFF inhibit Output voltage sense Point-of-Load-Alliance (POLA) compatible Available RoHS compliant PTH03020 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.

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 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 F 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 F of distributed capacitance at the load will improve the transient response. 5 1 A/s load step, 50 to 100% Iomax, Cout = 330 F. 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-TrackTM. This is because when the module is under Auto-TrackTM 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-TrackTM function 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. 10 NOTICE: Some models do not support all options.
