LX7104 Datasheet | Microsemi

.Microsemi . ® 1.4MHz 1.5A Asynchronous Buck Converter PRODUCTION DATASHEET DESCRIPTION The LX7104 is a 1.4MHz fixed Soft-start is built in, and current mode frequency, current mode, PWM buck (step- control provides fast transient response and down) DC-DC converter, capable of cycle-by-cycle current limit. Short circuit driving a 1.5A load with high efficiency, protection will be triggered when current is excellent line and load regulation. The over limit and FB is below 0.25V. device integrates a N-channel power The LX7104ISF is available in SOT23MOSFET switch with low on-resistance. 6 package. The converter accepts a wide input voltage range from 4.5V to 18V, and provides an output voltage adjustable typically from 0.81 to 15V.
