The CS51411 demonstration board is a 1.0 A/3.3 V buck regulator that operates at 260 or 520 kHz (CS51413). By providing clock signals to the SYNC input, the switching frequency may be synced to a higher frequency.

The XL6005 LED constant current driver is a fixed frequency PWM Boost (step-up) LED constant current driver capable of controlling Series 1W/3W/5W LED modules with outstanding line and load regulation.

LM1117 is a voltage regulator with low power consumption and a fixed output voltage of 2.85V, which is designed to meet 1A output current and complies with SCSI-II specifications. This device is the best choice for battery-powered applications.
