一.产品概述

---

   The CXSU6372 is a current mode boost DC-DC converter. It is PWM circuitry with built-in 0.08Ω  power MOSFET make this regulator highly power efficient. The internal compensation network also  minimizes as much as 6 external component counts. The non-inverting input of error amplifier connects   to a 0.6V precision reference voltage and internal soft-start function can reduce the inrush current.

              The CXSU6372 is available in the SOP-8L(EP) package and provides space-saving PCB for the application fields.
