LP3301 -1.5MHZ升压DC/DC背光驱动IC
LP3301 General Description
The LP3301 is a 1.5MHz PWM boost switching regulator designed for constant-Voltage driver applications.The LP3301 implements a constant frequency 1.5MHz PWM control scheme. The high frequency PWM operation also saves board space by reducing external component sizes. To improve efficiency, the feedback voltage is set to 1.25V.Highly integration and internal compensation network minimizes as 5 external component counts. Optimized operation frequency can meet the requirement of small LC filters value and low operation current with high efficiency.
