目录 1.产品概述 2.产品特点 3.应用范围 4.技术规格书下载(PDF文档) 一.产品概述 The CXSU6395E is a high efficiency, peak current control mode DC-DC boost converter. It supports up to 1A output current with an integrated low RDS(ON) (130mΩ) N-channel MOSFET and cycle by cycle current limit protection. The device can provide a USB 5V compliant power output from a single Li-ion battery. The boost converter runs in Pulse-Width Modulation (PWM) mode, at 1MHz fixed switching frequency to reduce output ripple, improve conversion efficiency. It allows for the use of small external components. At light load currents the converter enters Skipping Mode to maintain a high efficiency over a wide load current range. The build-in soft start circuitry minimizes the inrush current at start-up. Internal compensation network require only boost inductor, schottky diode, and input and output capacitors for CXSU6395E, save PCB area. The CXSU6395E is available in SOT-23-6L package. Standard product is Pb-free and Halogen-free. 二.产品特点 Input voltage range : 2.7~5.5V Continuous output current : 1.0A Switching frequency : 1MHz (Typ.)
