一.产品概述

---

 The CXSU6374 is a boost topology switching regulator for wide operating voltage applications. It provides built-in gate driver pin for driving an external N-MOSFET. The internal compensation network minimizes external component counts, and the non-inverting input of error amplifier connects to a 0.6V precision reference voltage. The CXSU6374 has internal soft start and programmable over current protection set by external resistance.
     The CXSU6374 is available in the small footprint SOT23-6L package to fit in space-saving PCB layout for miscellaneous application fields.
