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.
