1 / 5 page DC-DC CONVERTERS POLA Non-isolated 1 NEW Product File Name: pth12020.pdf Rev (07): 19 Dec 2005 2 YEAR WARRANTY All specifications are typical at nominal input, full load at 25 °C unless otherwise stated Cin = 560 µF, Cout = 0 µF 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. • 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 *Auto-track™ is a trade mark of Texas Instruments PTH12020 12 Vin single output SPECIFICATIONS International Safety Standard Approvals UL/cUL CAN/CSA-C22.2 No. 60950-1-03/UL 60950-1, File No. E174104 TÜV Product Service (EN60950) Certificate No. B 04 06 38572 044 CB Report and Certificate to IEC60950, Certificate No. US/8292/UL OUTPUT SPECIFICATIONS Voltage adjustability Suffix ‘W’ 1.2-5.5 Vdc (See Note 4) Suffix ‘L’ 0.8V-1.8 Vdc Setpoint accuracy ±2.0% Vo Line regulation ±5 mV typ.
