DESCRIPTION
The AT7577 allows introducing an additional adjustment for the Over Current Protection (OCP) and Over Voltage Protection (OVP). In this case the OCP and OVP value can be changed with help external resistors. The AT7577 provides all the active functions for a step-down (buck) switching regulator and is capable of driving 2A load with excellent line and load regulation. It includes an internal frequency compensation components and a fixed-frequency oscillator. Among other features are a guaranteed ±2% tolerance on an output voltage within the specified input voltages and output load conditions. External shutdown is included. The output switch includes cycle-by-cycle current limiting and thermal shutdown elements for a full protection under fault conditions. The high gain, internally frequency-compensated operational amplifiers were designed specifically to operate from a single power supply over a wide range of voltages.
