The LMS1587CSX-ADJ has many applications such as precision instrumentation and control, LED drivers, computers and peripherals, automotive, industrial, medical, process control and telecommunications.

The basic working principle of the LMS1587CSX-ADJ is based on a self contained oscillator-based current mode control loop. It uses a voltage reference, which is external and adjustable, as the output voltage control. An input voltage is applied by an internal P-channel MOSFET and converted to a constant current. This current is then applied to a resistive network generated output voltage.

The device uses a current sensing resistor to sense the current flow and a comparator to compare the current with the voltage. If the voltage is above the reference voltage, the output of the comparator is low and the internal MOSFET is turned off. This action stops the current and regulation is complete. If the voltage is below the reference voltage, the output of the comparator is high and the MOSFET is turned on, allowing the current to flow until the desired output voltage is achieved.

The LMS1587CSX-ADJ is designed for a wide variety of applications. It provides efficient power regulation at low cost in a tiny footprint for low voltage, low noise and ultra-high current applications. This makes it an ideal choice for wide range of applications from precision instrumentation and control to automotive, industrial, medical, process control and telecommunications.
