PTV03020 3.3 Vin single output DC-DC CONVERTERS • • • • • • • • • • • • POLA Non-isolated 1 NEW Product 18 A output current 3.3 Vin input voltage Wide-output voltage adjust (0.8 Vdc to 2.5 Vdc) Auto-track™ sequencing* Pre-bias start-up Efficiencies up to 96% Output ON/OFF inhibit Output voltage sense Vertical through-hole mounting Point-of-Load-Alliance (POLA) compatible Undervoltage lockout Available RoHS compliant The PTV03020 is a non-isolated dc-dc converter from Artesyn under the Point of Load Alliance (POLA) standard. The vertical mounting option of the PTV03020 module provides performance in less than 20% of the space that is required by alternative solutions. The Auto-Track™ 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. The PTV03020 has an input voltage of 2.95 Vdc to 3.6 Vdc and offers a wide 0.8 Vdc to 2.5 Vdc output voltage range with up to 18 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 = 680 µF and 22 µF(Ceramic), Cout = 0 µF OUTPUT SPECIFICATIONS GENERAL SPECIFICATIONS Voltage adjustability (See Note 4) 0.8-2.5 Vdc Setpoint accuracy (See Note 8) ±2.0% Vo Efficiency Line regulation ±5 mV typ.

Pin Length (0.150”) Output Voltage Code W = Wide Output Current 02 = 18 A Mechanical Package Always 0 Output Voltage Adjustment of the PTV03020 Series The ultra-wide output voltage trim range offers major advantages to users who select the PTV03020. 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 PTV03020 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 < 0.6 V 2 See Figure 1 for safe operating curve. 3 A 680 µF electrolytic input capacitor is required for proper operation as well as a 2 2µF high-frequency ceramic capacitor. The electrolytic capacitor must be rated for a minimum of 750 mA rms of ripple current. 4 An external output capacitor is not required for basic operation. Adding 33 0µF of distributed capacitance at the load will improve the transient response. 5 1A/µs load step, 50 to 100% Iomax, C3 = 330 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 197 for more details. 8 The set-point voltage tolerance is affected by the tolerance and stability of Rset. The stated limit is unconditionally met if Rset has a tolerance of 1% with 100/ºC or better temperature stability. 9 To order Pb-free (RoHS compatible) through-hole parts replace the mounting option ‘H’ with ‘D’, e.g. PTV03020WAD. 10 NOTICE: Some models do not support all options.
