LP3315
Description
The LP3315 is a 1.2MHz PWM boost switching regulator designed for constant-voltage boost applications. The LP3315 can drive a string of up to 30V. The LP3315 implements a constant frequency 1.2MHz PWM control scheme. The high frequency PWM operation also saves board space by reducing external ponent sizes. To improve efficiency, the feedback voltage is set to 1250m V, which reduces the power dissipation in the voltage setting resistor. Highly integration and internal pensation network minimizes as 5 external ponent counts. Optimized operation frequency can meet the requirement of small LC filters value and low operation current with high efficiency.
