WebBuffer with open-drain output. The 74LVC1G07 is a single buffer with open-drain output. Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices as translators in mixed 3.3 V and 5 V environments. Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times. WebFlyback converters are often used in switch-mode power supplies for AC/DC and DC/DC conversion, especially for the low-to-mid power range (about 2W to 100W). In this power range, flyback converters offer a very competitive size, cost, and efficiency ratio.
