PTV03010 3.3 Vin single output DC-DC CONVERTERS POLA Non-isolated 1 NEW Product 8 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 Efficiencies up to 93% Output ON/OFF inhibit Vertical through-hole mounting Point-of-Load-Alliance (POLA) compatible Undervoltage lockout Available RoHS compliant The PTV03010 is a non-isolated dc-dc converter from Artesyn under the Point of Load Alliance (POLA) standard. The vertical mounting option of the PTV03010 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 PTV03010 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 8 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 and 10 F (Ceramic), 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 (See Note 8) 2.0% Vo Radiated immunity EN61000-4-3 Line regulation 5 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 PTV03010 converter leaves the factory the output has been adjusted to the default voltage of 0.8 V. NNootteess EFFICIENCY TABLE (I = I MAX ) O O 1 Remote ON/OFF.

Vo = 2.5 V 93 2 See Figure 1 for safe operating curve. 3 A 100 F electrolytic input capacitor is required for proper operation as Vo = 1.8 V 90 well as a 10 F high-frequency ceramic capacitor. The electrolytic capacitor must be rated for a minimum of 300 mArms of ripple current. Vo = 1.5 V 89 4 An external output capacitor is not required for basic operation. Adding 100 F of distributed capacitance at the load will improve the transient Vo = 1.2 V 87 response. 5 1A/s load step, 50 to 100% I , C3 = 100 F. omax Vo = 1.0 V 85 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 modules output held off using the Inhibit pin. Refer to Application Note 194 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. PTV03010WAD. 10 NOTICE: Some models do not support all options.
