PTH03050 3.3 Vin single output DC-DC CONVERTERS POLA Non-isolated 1 NEW Product 6 A output current 3.3 V input voltage Wide-output voltage adjust (0.8 Vdc to 2.5 Vdc) Auto-track sequencing* Pre-bias start-up capability Efficiencies up to 94% Output ON/OFF inhibit Output voltage sense Point-of-Load-Alliance (POLA) compatible Available RoHS compliant 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 DSPs, FPGAs and ASICs requiring controlled power-up and power-down. Other industry leading features include pre-bias start-up capability and efficiencies up to 94%. The PTH03050 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 6 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 = 100 F, C = 0 F in out OUTPUT SPECIFICATIONS EMC CHARACTERISTICS Voltage adjustability (See Note 4) 0.8-2.5 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 10 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 2.5 Vdc. When the PTH03050 converter leaves the factory the output has been adjusted to the default voltage of 0.8 V. NNootteess EFFICIENCY TABLE (I = 4 A) O 1 Remote ON/OFF.

The Vo = 1.2 V 88% capacitor must be rated for a minimum of 300 mA rms of ripple current. 4 An external output capacitor is not required for basic operation.

Vo = 2.0 V 92% 7 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 Vo = 2.5 V 94% 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 modules output held off using the Inhibit pin. Refer to Application Note 153 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. PTH03050WAZ. To order Pb-free (RoHS compatible) through-hole parts replace the mounting option H with D, e.g. PTH03050WAD. 10 NOTICE: Some models do not support all options.
