PTH12020 12 Vin single output DC-DC CONVERTERS POLA Non-isolated 1 NEW Product • 18 A output current • 12 V input voltage • Wide-output voltage adjust • 1.2 Vdc to 5.5 Vdc for suffix ‘W’ and 0.8 Vdc to 1.8 Vdc for suffix ‘L’ • Auto-track™ sequencing* • Margin up/down controls • Efficiencies up to 95% • Output ON/OFF inhibit • Output voltage sense • Point-of-Load-Alliance (POLA) compatible • Available RoHS compliant The PTH12020 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 margin up/down controls and efficiencies up to 95%. The PTH12020 has an input voltage of 10.8 Vdc to 13.2 Vdc and offers a wide output voltage range adjustable with external trim resistor, allowing 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 = 560 µF, Cout = 0 µF OUTPUT SPECIFICATIONS Voltage adjustability (See Note 4) SPECIFICATIONS EMC CHARACTERISTICS Suffix ‘W’ Suffix ‘L’ Setpoint accuracy 1.2-5.5 Vdc 0.8V-1.8 Vdc ±2.0% Vo Electrostatic discharge Conducted immunity Radiated immunity EN61000-4-2, IEC801-2 EN61000-4-6 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 1.2 Vdc to 5.5 Vdc. When the PTH12020 converter leaves the factory the output has been adjusted to the default voltage of 1.2 V.

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). See Figures 1, 2 and 3 for safe operating curves. A 560 µF electrolytic input capacitor is required for proper operation. The capacitor must be rated for a minimum of 800 mA rms of ripple current. An external output capacitor is not required for basic operation. Adding 330 µF of distributed capacitance at the load will improve the transient response. 1 A/µs load step, 50 to 100% Iomax, Cout = 330 µF. If utilized Vout will track applied voltage by ±0.3 V (up to Vo set point). Tape and reel packaging only available on the surface-mount versions. To order Pb-free (RoHS compatible) surface-mount parts replace the mounting option ‘S’ with ‘Z’, e.g. PTH12020WAZ. To order Pb-free (RoHS compatible) through-hole parts replace the mounting option ‘H’ with ‘D’, e.g. PTH12020WAD. NOTICE: Some models do not support all options.
