|
Overview
The LX7104ISF is a 1.4MHz fixed frequency, current mode, PWM buck (stepdown) DC-DC converter, capable of driving a 1.5A load with high efficiency, excellent line and load regulation. The device integrates a N-channel power MOSFET switch with low on-resistance. 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. Soft-start is built in, and current mode control provides fast transient response and cycle-by-cycle current limit. Short circuit protection will be triggered when current is over limit and FB is below 0.25V. The LX7104ISF is available in SOT23-6 package.
