Mingjiada Electronics [Supplying IC in Stock] MaxLinear XR76112ELTR 12A Synchronous step-down regulator, switching regulator
For details
The XR76112ELTR is a high-efficiency, low-noise, synchronous step-down DC-DC converter controller produced by Exar Corporation (now part of MaxLinear). This device adopts a current-mode control architecture and is suitable for power management applications that require high efficiency and high stability.
The XR76112ELTR adopts a current-mode control architecture, providing fast transient response and excellent stability. It integrates a high-precision error amplifier and a PWM controller internally, allowing users to build an efficient power supply system through external MOSFETs and inductors. This controller supports a soft-start function, which can prevent current surges during startup. It also features multiple protection mechanisms such as overcurrent protection, over-temperature protection, and undervoltage locking to ensure the reliable operation of the system.
In addition, the XR76112ELTR offers an adjustable switching frequency function, allowing users to select the optimal operating frequency based on specific application requirements, thereby achieving a balance between efficiency and the size of external components. Its light-load high-efficiency mode can automatically enter an energy-saving state under low-load conditions, further reducing power consumption.
The XR76112ELTR also supports remote voltage monitoring function, which improves the accuracy of output voltage regulation through remote sampling. It is suitable for applications with high requirements for voltage stability, such as precision analog circuits and high-speed digital systems.
