Description
L6728A 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 VFDFPN 10 package.
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 protections
◾ VSEN disconnection protection
◾ Oscillator internally fixed at 600 kHz
◾ LS-LESS to manage pre-bias start-up
◾ Adjustable output voltage
◾ Disable function
◾ Internal soft-start
◾ VFDFPN 10 package
Applications
◾ Memory and termination supply
◾ Subsystem power supply (MCH, IOCH, PCI)
