Table 1. Device summary

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 VIN 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 RdsON 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.
