The LP6230A can drive a string of up to 30V. The LP6230A implements a constant frequency 1.2MHz PWM control scheme. The high frequency PWM operation also saves board space by reducing external component sizes. The LP6230A features automatic shifting to pulse frequency modulation mode at light loads.Highly integration and internal compensation network minimizes as 6 external component counts. Optimized operation frequency can meet the requirement of small LC filters value and low operation current with high efficiency. The LP6230A includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The LP6230A is available in a small 8-pin MSOP8 package.
