3 Description
The MX8134 is a monolithic IC designed for a step-down DC/DC converter with low EMI signature, and own the ability of driving a 3A load without additional transistor. It saves board space. The MX8134 also can run at 92% duty cycle for low dropout operation, and Internal soft-start results in small inrush current extending battery life in portable systems. As a protection function, it has cycle by cycle peak current limit function, short protection function, thermal shutdown function. The device is available in a 8-pin small profile ESOP8 package.
