L6728D Single phase PWM controller with Power Good
L6728D is a single-phase step-down controllerwith integrated high-current drivers that providescomplete control logic and protection to simplifythe design of general DC-DC converters by usinga compact DFN10 package.Device flexibility allows the management ofconversions with power input (VIN) as low as1.5 V, and device supply voltage ranging from 5 Vto 12 V.The L6728D provides a simple control loop withvoltage mode EA. The integrated 0.8 V referenceallows 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 levelovercurrent protection, as well as overvoltage andundervoltage protection. Current information ismonitored across the low-side MOSFET RDS(on),eliminating the need for expensive and spaceconsumingsense resistors.A PGOOD output easily provides real-timeinformation on output voltage status, through theVSEN dedicated output monitor
