PTH05020 5 Vin single output DC-DC CONVERTERS POLA Non-isolated 1 NEW Product 22 A output current 5 V input voltage Wide-output voltage adjust (0.8 Vdc to 3.6 Vdc) Auto-track sequencing* Margin up/down controls Pre-bias start-up capability Efficiencies up to 96% Output ON/OFF inhibit Output voltage sense Point-of-Load-Alliance (POLA) compatible Available RoHS compliant The PTH05020 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 DSPs, FPGAs and ASICs 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 96%. The PTH05020 has an input voltage of 4.5 Vdc to 5.5 Vdc and offers a wide 0.8 Vdc to 3.6 Vdc output voltage range with up to 22 A output current, which allows for maximum design flexibility and a pathway for future upgrades. 2 YEAR WARRANTY All specifications are typical at nominal input, full load at 25 C unless otherwise stated SPECIFICATIONS C = 1000 F, C = 0 F in out OUTPUT SPECIFICATIONS EMC CHARACTERISTICS Voltage adjustability (See Note 4) 0.8-3.6 Vdc Electrostatic discharge EN61000-4-2, IEC801-2 Conducted immunity EN61000-4-6 Setpoint accuracy 2.0% Vo Radiated immunity EN61000-4-3 Line regulation 5 mV typ.

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 3.6 Vdc. When the PTH05020 converter leaves the factory the output has been adjusted to the default voltage of 0.8 V. NNootteess EFFICIENCY TABLE (I = 10 A) O 1 Remote ON/OFF. Positive Logic OUTPUT VOLTAGE EFFICIENCY ON: Pin 3 open or V > Vin - 0.5 V OFF: Pin 3 GND or V < 0.8 V (min - 0.2 V). Vo = 1.0 V 88% 2 See Figure 1 for safe operating curve. 3 A 1,000 F electrolytic input capacitor is required for proper operation. Vo = 1.2 V 90% The capacitor must be rated for a minimum of 700 mA rms of ripple current. Vo = 1.5 V 91% 4 An external output capacitor is not required for basic operation. Adding 330 F of distributed capacitance at the load will improve the transient Vo = 1.8 V 92% response. 5 1 A/s load step, 50 to 100% I , C = 330 F. omax out Vo = 2.0 V 93% 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 Vo = 2.5 V 94% 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 Vo = 3.3 V 96% 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 modules output held off using the Inhibit pin. Refer to Application Note 156 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. PTH05020WAZ. To order Pb-free (RoHS compatible) through-hole parts replace the mounting option H with D, e.g. PTH05020WAD. 10 NOTICE: Some models do not support all options.
