PTH03050 3.3 Vin single output DC-DC CONVERTERS POLA Non-isolated 1 • 6 A output current NEW Product • 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 RoHScompliant 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 DSP’s, FPGA’s and ASIC’s 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 Vdcand offers a wide 0.8 Vdc to 2.5 Vdcoutput 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 µF, C = 0 µF 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. Positive Logic ON: Pin 3 open; or V >Vin - 0.5 V OUTPUT VOLTAGE EFFICIENCY OFF: Pin 3 GND; or V <0.8 V (min - 0.2 V). 2 See Figure 1 for safe operating curve. Vo = 1.0 V 87% 3 A 100 µF electrolytic input capacitor is required for proper operation. The capacitor must be rated for a minimum of 300 mA rms of ripple current. Vo = 1.2 V 88% 4 An external output capacitor is not required for basic operation. Adding 100 µF of distributed capacitance at the load will improve the transient Vo = 1.5 V 90% response. 5 1 A/µs load step, 50 to 100% Iomax, Cout= 100 µF. Vo = 1.8 V 91% 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 = 2.0 V 92% 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 = 2.5 V 94% 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 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.
