L6728 - STMicroelectronics

L6728 Single phase PWM controller

L6728 is a single-phase step-down controller with integrated high-current drivers that provides complete control logic and protection to realize in a simple way general DC-DC converters by using a compact DFN10 package. Device flexibility allows managing conversions with power input VIN as low as 1.5 V and device supply voltage ranging from 5 V to 12 V. L672.
