Update: 30 September, 2023
The L6728D is a single-phase step-down controller with integrated high-current drivers that provides complete control logic and protection to simplify the design of general DC-DC converters by using a compact DFN10 package. Device flexibility allows the management of conversions with power input (VIN) as low as 1.5 V, and device supply voltage ranging from 5 V to 12 V. The L6728D provides a simple control loop with voltage mode EA. The integrated 0.8 V reference allows output voltages regulation with ±0.8% accuracy over line and temperature variations. The oscillator is internally fixed to 300 kHz. The L6728D provides programmable dual level overcurrent protection, as well as overvoltage and undervoltage protection. Current information is managed by LSLess to manage pre-bias startup.
