   产品概述 返回TOPZds嘉泰姆

           The CXSU63025 series is a CMOS step-up switching regulator which mainly consists of a reference voltage source, an oscillation circuit,an error amplifier, a phase compensation circuit,a PWM/PFM switching control circuit. With an external low-ON-resistance Nch Power MOS,this product is applicable to applications requiring high efficiency and high output current. 

         The CXSU63025 series switches its operation to the PFM control circuit whose duty ratio is 15% with to the PWM/PFM switching control circuit under a light load and to prevent decline in the efficiency by IC operation current.
