STMicroelectronics L6728H
L6728H 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. The integrated 0.8 V reference allows regulating output voltages with ±0.8% accuracy over line and temperature variations. L6728H provides simple control loop with voltage mode EA.| Part No. | L6728H |

DESCRIPTION
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. Oscillator is internally fixed to 300 kHz. L6728H provides programmable dual level over current protection as well as over and under voltage protection. Current information is monitored across the low-side MOSFET RDS(on) saving the use of expensive and spaceconsuming sense resistors. PGOOD output easily provides real-time information on output voltage status, through VSEN dedicated output monitor.
