The CXSU6383 is a step-up converter that provides a boosted output voltage from a low voltage source. Because of its proprietary design, it starts up at a very low input voltage down to 850mV. Along with its 10uA ultra-low no load input current, it is an ideal choice for single cell alkaline/NiMH battery operations. A switching frequency of 1MHz minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors. The current mode PWM design is internally compensated, reducing external parts count. CXSU6383 is housed in a tiny SOT23-5 package 二.产品特点 ◆0.85V启动 ◆空载待机电流<20uA ◆10μA No Load Supply Current ◆Low Vin Start-up Voltage down to 850mV ◆Capable of delivering 300mA IOUT at Vin=3.0V, V out=3.3V ◆1MHz Switching Frequency ◆Input boost-strapping allows using small cap ◆Low Noise PWM control ◆Internally Compensated Current Mode Control ◆Internal Synchronous Rectifier ◆Logic Control Shutdown (IQ<1uA) ◆Available in SOT23-5 三.应用范围 ◆智能电视遥控器鼠标 ◆其他电池供电类设备
