目录产品概述 返回TOP The CXLE81105 boost converter contains a 0.46Ω internal switch. The IC operates at constant frequency 600 kHz, allowing the use of tiny, low cost and low height inductors and capacitors. The IC operates from a 2.7V to 7V supply voltage. High inrush current at start-up is eliminated using large compensation capacitor. Constant frequency current mode PWM architecture results in low, predictable output noise. The CXLE81105 includes cycle-by-cycle 700mA current limit to maximize inductor current and over-temperature protection circuit. The over-voltage protection will be enabled when VOUT exceeds 26V. The current of LED is set by a resistor connected between FB and GND. The CXLE81105 is available in TDFN2X2-6 package.产品特点 返回TOP „ 2.7V to 7V Input Voltage Range „ 600kHz Operating Frequency „ 26V High Output Voltage „ Over-Voltage Protection „ 5kHz to 100kHz PWM Brightness Control „ Built-in Cycle-by-Cycle Current Limit „ 0.2V Low Reference Voltage „ TDFN2X2-6 Package 应用范围 返回TOP „ Cellular Phone „ LED Module „ Compact Back Light Module 技术规格书（产品PDF) 返回TOP 需要详细的PDF规格书请扫一扫微信联系我们，还可以获得免费样品以及技术支持！
