Description

The AX3007-50ESA is a monolithic IC designed for a step-down DC/DC converter. It is part of the AX3007 series and falls under the product category of IC Chips. This IC has the ability to drive a 2A load without the need for an additional transistor, which helps save board space. It also features an external shutdown function that can be controlled by logic level to enter standby mode.

With internal compensation, the AX3007-50ESA offers good line and load regulation for feedback control without the need for external design. It also provides thermal shutdown protection to prevent damage from over temperature operating. Additionally, it has a current limit function to protect against over current operating of the output switch. In case of current limit function activation and a VFB drop below 0.5V, the switching frequency will be reduced.
