一.产品概述q5X嘉泰姆


  The CXSU6381 is a current mode boost DC-DC converter with PWM/PSM control. Its PWM circuitry with built-in 30mΩ high side switch and 30mΩ 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. q5X嘉泰姆
