Description
L6726A is a single-phase step-down controller
with integrated high-current drivers that provides
complete control logic, protections and reference
voltage to realize in an easy and simple way
general DC-DC converters by using a compact
SO-8 package.
Device flexibility allows managing conversions
with power input V
IN
as low as 1.5V and device
supply voltage ranging from 5V to 12V.
L6726A provides simple control loop with trans-
conductance error amplifier. The integrated 0.8V
reference allows regulating output voltage with
±1% accuracy over line and temperature
variations. Oscillator is internally fixed to 270kHz.
L6726A provides programmable over current
protection. Current information is monitored
across the Low-Side mosfet R
dsON
saving the use
of expensive and space-consuming sense
resistors.
FB disconnection protection prevents excessive
and dangerous output voltages in case of floating
FB pin.
