L6728  
Single phase PWM controller with PowerGOOD  
Features  
Flexible power supply from 5V to 12V  
Power conversion input as low as 1.5V  
0.8V internal reference  
0.8% output voltage accuracy  
High-Current integrated drivers  
PowerGOOD output  
VFQFPN 10  
Sensorless and programmable OCP across  
Low-Side R  
Description  
dsON  
OV / UV protections  
L6728 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 VFQFPN 10 package.  
VSEN disconnection protection  
Oscillator internally fixed at 300kHz  
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 1.5V and device  
IN  
supply voltage ranging from 5V to 12V.  
Internal Soft-Start  
VFQFPN 10 package  
L6728 provides simple control loop with voltage  
mode EA. The integrated 0.8V reference allows  
regulating output voltages with 0.8% accuracy  
over line and temperature variations. Oscillator is  
internally fixed to 300kHz.  
Applications  
Memory and termination supply  
Subsystem power supply (MCH, IOCH, PCI...)  
CPU & DSP power supply  
L6728 provides programmable dual level over  
current protection as well as over and under  
voltage protection. Current information is  
monitored across the Low-Side MOSFET RdsON  
saving the use of expensive and space-  
consuming sense resistors.  
Distributed power supply  
General DC / DC converters  
PGOOD output easily provides real-time  
information on Output Voltage status, through  
VSEN dedicated output monitor.
