Description
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.
Features
◾ Flexible power supply from 5 V to 12 V
◾ Power conversion input as low as 1.5 V
◾ 0.8 V internal reference
◾ 0.8% output voltage accuracy
◾ High-current integrated drivers
◾ Power Good output
◾ Sensorless and programmable OCP across
low-side RDS(on)
◾ OV / UV protection
◾ VSEN disconnection protection
◾ Oscillator internally fixed at 300 kHz
◾ LSLess to manage pre-bias startup
◾ Adjustable output voltage
◾ Disable function
◾ Internal soft-start
◾ DFN10 package
Applications
◾ Memory and termination supply
◾ Subsystem power supply (MCH, IOCH, PCI,
etc.)
◾ CPU and DSP power supply
◾ Distributed power supply
◾ General DC-DC converters
