Transformers Built For Switching Regulators

Designed to provide maximum power while serving as switching regulators in flyback, buck-and-boost circuit designs, TOL Series of 15W power transformers can handle universal ac inputs of 85 to 265 vac, 47 to 440 Hz. Five members of this series offer continuous operating currents ranging from 3A to 1A with output voltages ranging from 5V to 15V. Peak-to-peak currents range from 4A to 2A and peak wattages are from 20W to 30W. Typical primary output inductance range is 700 to 1060 µH at 100 kHz and 0.250 Vrms.
