微源半导体 LP3320 SOT23-6/DFN-6(2*2) 用于串联11PCS白色LED的高性能恒流开关稳压器
General description The LP3320 is a 1.0MHz PWM boost switching regulator designed for constant-current white LED driver applications. The LP3320 can drive a string of up to 11 white LEDs in series, ensuring uniform brightness and eliminating several ballast resistors. The LP3320 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 250mV, 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. Features ◆ Up to 94% efficiency Application ◆ WLED Backlight driver ◆ OLED Backlight driver ◆ PDA ◆ MID
◆ Shut-down current:<1uA
◆ Output voltage Up to 37V
◆ Internal Compensation, Soft-start
◆ Support down to 1% Dimming Duty Cycle
◆ 1.0MHz fixed frequency switching
◆ High switch on current:1.5A
◆ Available in SOT23-6&TDFN-6(2mm×2mm) Package
