The MAX17512 IC is a fully integrated valley current regulatorwith a modified constant on-time control schemethat emulates hysteretic-mode behavior for transients.It integrates both the high-side and low-side switchesthat are designed to deliver load currents up to 6A. Thedevice supports a 6.5V to 18V wide input voltage range.The device accepts an external current-reference signal(ICMD) and regulates the inductor current valley such thatit closely follows the reference signal. This allows dynamicvoltage scheduling and advanced power management,reducing system power consumption. Example applicationsinclude envelope tracking in base stations, dynamicvoltage scheduling in industrial control, and lighting.
