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 DSPs, FPGAs and ASICs 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 2 YEAR WARRANTY for future upgrades.

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 NNootteess EFFICIENCY TABLE (I = 12 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 < 0.6 V Vo = 2.5 V 95 2 See Figure 1 for safe operating curve. 3 A 680 F electrolytic input capacitor is required for proper operation as Vo = 1.8 V 92 well as a 2 2F high-frequency ceramic capacitor. The electrolytic capacitor must be rated for a minimum of 750 mA rms of ripple current. Vo = 1.5 V 90 4 An external output capacitor is not required for basic operation. Adding 33 0F of distributed capacitance at the load will improve the transient Vo = 1.2 V 88 response. 5 1A/s load step, 50 to 100% I , C3 = 330 F. omax Vo = 1.0 V 86 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 = 0.8 V 83 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 modules 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 R . The stated limit is unconditionally met if R has a tolerance of set set 1% with 100/C 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.
