The MxL7606P, MxL7612P, MxL7620P, and MxL7630P (MxL76xxP family) are compact, high-current step-down intelligent point-of-load
(iPOL) buck regulators. The MxL76xxP devices feature a PMBus® interface supporting high precision telemetry for IIN, VIN, VOUT, IOUT,
PIN, and POUT and dynamic voltage scaling. The MxL76xxP family is rated at 6A, 12A, 20A, and 30A with a wide input voltage range from
2.7V to 16V, which allows for single supply operation from industry standard 3.3V, 5V, and 12V rails.
The MxL76xxP family features a proprietary constant on-time (COT) control scheme to provide extremely fast transient response using
ceramic or electrolytic output capacitors. The control loop also provides excellent line and load regulation.
High frequency operation (up to 2MHz) minimizes inductor and output capacitance, which results in the highest possible power density.
No external compensation circuitry is required, simplifying circuit implementation and reducing overall component count. A selectable
power saving mode allows you to operate in discontinuous mode (DCM) at light current loads, thereby significantly increasing the converter
efficiency.
A host of protection features, including overcurrent, output overvoltage, over temperature, short-circuit, high-side short, and undervoltage
lockout (UVLO) help achieve safe operation under abnormal operating conditions.
