1 / 7 page  LP6226/A-04 May.-2013 Email: marketing@lowpowersemi.com www.lowpowersemi.com Page 1 of 7 Preliminary Datasheet LP6226/A High Efficiency Boost DC/DC Convertor General Description The LP6320A is a 1MHz PWM boost switching regulator designed for constant-voltage boost applications. The LP6226 can drive a string of up to 30V. The LP6226 implements a constant frequency 1MHz PWM control scheme. The high frequency PWM operation also saves board space by reducing external component sizes. The LP6226 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 LP6226 includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The LP6226 is available in a small SOT23-6 package.
