一.产品概述

---

      The CXSU6396E is a high efficiency, high power, peak current mode step-up converter. Internal 0.35Ω HV power MOSFET with Min. 1A current limit. For portable device with Li-ion battery application, 

     CXSU6396E could output typical 12V / 200mA ~300mA from 3.3V~5V input. The boost converter CXSU6396E runs in Pulse-Width Modulation (PWM) mode, at 1.2MHz 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. 

      The CXSU6396E is available in SOT-23-5L package. Standard product is Pb-free and Halogen-free.
