■ 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

DFN10

■ Sensorless and programmable OCP across

low-side R

Description

DS(on)

■ OV / UV protections

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.

■ VSEN disconnection protection

■ Oscillator internally fixed at 300 kHz

■ LSless to manage pre-bias start-up

■ Adjustable output voltage

■ Disable function

Device flexibility allows managing conversions

with power input V as low as 1.5 V and device

supply voltage ranging from 5 V to 12 V.

■ Internal soft-start

■ DFN10 package

L6728H provides simple control loop with voltage

mode EA. The integrated 0.8 V reference allows

regulating output voltages with 0.8% accuracy

over line and temperature variations. Oscillator is

internally fixed to 300 kHz.

Applications

■ Memory and termination supply

■ Subsystem power supply (MCH, IOCH, PCI...)

■ CPU and DSP power supply

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 R

saving the use of expensive and space-

consuming sense resistors.

DS(on)

■ Distributed power supply

■ General DC-DC converters

PGOOD output easily provides real-time

information on output voltage status, through

VSEN dedicated output monitor.
