L6728AH  
High frequency 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  
VFQFPN 10  
Sensorless and programmable OCP across  
low-side R  
Description  
DS(on)  
OV / UV protections  
L6728AH 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.  
VSEN disconnection protection  
Oscillator internally fixed at 600 kHz  
LS-LESS 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  
IN  
supply voltage ranging from 5 V to 12 V.  
Internal soft-start  
VFDFPN 10 package  
L6728AH 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 600 kHz.  
Applications  
Memory and termination supply  
Subsystem power supply (MCH, IOCH, PCI)  
CPU and DSP power supply  
Distributed power supply  
L6728AH 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)  
General DC / DC converters  
PGOOD output easily provides real-time  
information on output voltage status, through  
VSEN dedicated output monitor.
