产品概述
描述
The PM7744 is a single phase step-down controller with complete control logic and protection to realize in a simple way general DC-DC converters by using a compact 3 x 3 mm QFN package.
The PMBus™ interface allows device configuration and output voltage, current and controller temperature monitoring.
The PM7744 device features a dedicated control loop managing high frequency repetitive load transients maintaining the regulation in all operative conditions.
Remote sensing for the regulated voltage allows maintaining 0.5% accuracy on the regulated voltage overload and line variations.
The PM7744 device is available in a VFQFPN16, 3 x 3 mm package.
