微源半导体 LP3316 SOT23-5 1.2MHz、30V/1.4A高性能升压转换器

General description

The LP3316 is a 1.2MHz PWM boost switching regulator designed for constant-voltage boost applications. 

The LP3316 can drive a string of LED up to 30V. The LP3316 implements a constant frequency 1.2MHz PWM control scheme. The high frequency PWM operation also saves board space by reducing external component size. To improve efficiency, the feedback voltage is set to 1230 mV, which reduces the power dissipation at the voltage setting resistor. 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.
