PTH05050 5 Vin single output DC-DC CONVERTERS • • • • • • • • • • POLA Non-isolated 1 NEW Product 6 A output current 5 V input voltage Wide-output voltage adjust (0.8 Vdc to 3.6 Vdc) Auto-track™ sequencing* 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 The PTH05050 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 95%. The PTH05050 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 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 Cin = 100 µF, Cout = 0 µF OUTPUT SPECIFICATIONS Voltage adjustability EMC CHARACTERISTICS (See Note 4) Setpoint accuracy 0.8-3.6 Vdc ±2.0% Vo Line regulation ±10 mV typ.

Pin Length (0.140”) A = Surface-Mount Tin/Lead Solder Ball Output Voltage Code W = Wide Output Voltage Adjustment of the PTH05050 Series The ultra-wide output voltage trim range offers major advantages to users who select the PTH05050. 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 PTH05050 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 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. 4 An external output capacitor is not required for basic operation. Adding 100 µF of distributed capacitance at the load will improve the transient response. 5 1 A/µs load step, 50 to 100% Iomax, Cout = 100 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-Track™ 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-Track™ function must either be disabled, or the module’s output held off using the Inhibit pin. Refer to Application Note 158 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. PTH05050WAZ. To order Pb-free (RoHS compatible) through-hole parts replace the mounting option ‘H’ with ‘D’, e.g. PTH05050WAD. 10 NOTICE: Some models do not support all options.
