LP6229 微源升压转换器 SOT23-6封装
General Description
The LP6229 is a 1MHz PWM boost switching regulator designed for constant-voltage boost applications. The LP6229 output voltage up to 9V. The LP6229implements a constant frequency 1MHz PWM control scheme. The high frequency PWM operation also saves board space by reducing external component sizes. The LP6229 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 LP6229 includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The LP6229 is available in a small SOT23-6package.
