LP6235B6F数据手册LPSemi中文资料规格书

描述 Description

he LP6320A is a 1.2MHz PWM boost switching regulator designed for constant-voltage boost applications. The LP6235 can drive a string of up to 5.5V. The LP6235 implements a constant frequency 1.2MHz PWM control scheme. The high frequency PWM operation also saves board space by reducing external component sizes. The LP6235 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 LP6235 includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The LP6235 is available in a small SOT23-6 package.
