LPSemi/微源半导体 LP3325B6F SOT23-6 高效升压DC/DC变换器
General Description
The LP3325B6F is a 1.0MHz PWM boost switching regulator designed for constant-current white LED driver applications. The LP3325B6F can drive a string of up to 11 white LEDs in series, ensuring uniform brightness and eliminating several ballast resistors. The LP3321 implements a constant frequency 1.0MHz 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 200mV, which reduces the power dissipation in the current setting resistor. 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.
Applications
◆ WLED Backlight driver
◆ OLED Backlight driver
◆ PDA
◆ MID
