LP3302S七九八电子供应

The LP3302S is a 1.2MHz PWM boost switching regulator designed for constant- current white LED driver applications. The LP3302S can drive a string of up to 7 white LEDs from a 3.0V supply or 24 white LEDs from a 5V supply in series, ensuring uniform brightness and eliminating several ballast resistors. The LP3302S implements a constant frequency 1.2MHz PWM control scheme. The high requency 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 efficiencyLP3301，LP3302，LP3303，LP4054，LP3120，LP3204，LP3208，LPW5205，LPW5206，LP28200，LP系列产品供应，咨询：0755-23816294， 15999509062 丁先生 QQ:377142295
