The LM2587S-3.3/NOPB is a synchronous mode DC-DC converter designed to provide a wide input voltage range and high efficiency. The output voltage is sensed by an internal feedback loop and then compared to the voltage on the external VOUT pin. The difference between these two voltages forms the error signal, which is then amplified and used to modulate an integrated enhancement mode P-MOSFET switch.

The P-MOSFET switch then charges the output capacitor and produces the output voltage. To ensure a smooth transition between the switching cycles, an internal soft-start circuit limits the peak current at the switch source during startup and provides a constant voltage to the output capacitor. The frequency of the switching cycles is adjustable, allowing optimization of the device performance and matching to the system characteristics.
