一.产品概述USg嘉泰姆


  The CXSU6380 CXSU6380B is a current mode synchronous boost DC-DC converter with PWM/PSM control. Its PWM circuitry with built-in 40mΩ high side switch and 40mΩ low side switch make this regulator highly power efficient. The internal compensation network also minimizes external component counts to only 6. An internal 0.6V voltage is connected to error amplifier the non-inverting input as precision reference voltage. Built-in soft-start function can reduce the inrush current.  USg嘉泰姆
