L6728H  
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 protections  
L6728H is a single-phase step-down controller  
with integrated high-current dvers that provides  
complete control logic and protection to realize in  
a simple way generaDC-DC converters by using  
a compact DFN0 package.  
VSEN disconnection protection  
Oscillator internally fixed at 300 kHz  
LSless to manage pre-bias start-up  
Adjustable output voltage  
Disable function  
Device flexbility allows managing conversions  
with poer input V as low as 1.5 V and device  
IN  
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 spply  
Subsystem power supp(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.
