L6728D  
Single-phase PWM controller with Power Good  
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  
DFN10  
■ Sensorless and programmable OCP across  
low-side R  
Description  
DS(on)  
■ OV / UV protection  
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.  
■ VSEN disconnection protection  
■ Oscillator internally fixed at 300 kHz  
■ LSLess to manage pre-bias startup  
■ Adjustable output voltage  
■ Disable function  
Device flexibility allows the management of  
conversions with power input (V ) as low as  
IN  
1.5 V, and device supply voltage ranging from 5 V  
to 12 V.  
■ Internal soft-start  
■ DFN10 package  
The L6728D provides a simple control loop with  
voltage mode EA. The integrated 0.8 V reference  
allows output voltages regulation with 0.8%  
accuracy over line and temperature variations.  
The oscillator is internally fixed to 300 kHz.  
Applications  
■ Memory and termination supply  
The L6728D provides programmable dual level  
overcurrent protection, as well as overvoltage and  
undervoltage protection. Current information is  
■ Subsystem power supply (MCH, IOCH, PCI,  
etc.)  
■ CPU and DSP power supply  
■ Distributed power supply  
■ General DC-DC converters  
monitored across the low-side MOSFET R  
,
DS(on)  
eliminating the need for expensive and space-  
consuming sense resistors.  
A PGOOD output easily provides real-time  
information on output voltage status, through the  
VSEN dedicated output monitor.
