PTH03020 3.3 Vin single output DC-DC CONVERTERS POLA Non-isolated • 22 A output current • 3.3 V input voltage • Wide-output voltage adjust (0.8 Vdc to 2.5 Vdc) • Auto-track™ sequencing* • Margin up/down controls • 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 1 NEW Product The PTH03020 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, pre-bias start-up capability and efficiencies up to 95%. The PTH03020 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 22 A output current, which allows for maximum design flexibility and a pathway for future upgrades. All specifications are typical at nominal input, full load at 25 °C unless otherwise stated Cin = 1000 µF, Cout = 0 µF 2 YEAR WARRANTY SPECIFICATIONS OUTPUT SPECIFICATIONS Voltage adjustability (See Note 4) 0.8-2.5 Vdc Setpoint accuracy ±2.0% Vo Line regulation ±5 mV typ.
