The CXSU6382 is a high efficiency step-up converter that is capable of delivering up to 12W of output power. Its switching frequency can be externally programmed up to 1MHz. Current mode control makes it suitable with low ESR small ceramic output capacitor and provides small output current. Capable of delivering up to 2.1A of output current at 5V output from input down to 3V, it is an ideal solution for applications with Li-Ion batteries, such as portable power banks. CXSU6382 is housed in an ESOP8 package.
