Working Principle

The XR76208ELMTR-F DC-DC buck regulator utilizes a high-side Gate Driver, coupled with an Active Voltage Positioning (AVP) loop, to achieve fast transient response and excellent line and load regulation. It also supports output voltages as low as 0.6V and as high as 6.6V with up to 8A of load current. It works by taking the input voltage and converting it to a constant output voltage. The regulator uses an internal voltage reference to control the switching frequency, provide a tight line and load regulation, and eliminates the need for an external reference. The AVP loop maximizes efficiency by actively managing the ON and OFF times of the internal MOSFET\'s. The XR76208ELMTR-F regulator also incorporates over-voltage and current protection.
