Description
L6727 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 1.5 V and device supply
voltage in the range of 5 V to 12 V.
L6727 provides simple control loop with
voltagemode error-amplifier. The integrated 0.8 V reference allows regulating output
voltages with ±1 % accuracy over line and temperature variations. Oscillator is internally fixed to 300 kHz.
L6727 provides programmable over current protection as well as over and under
voltage protection. Current information is monitored across the low-side
MOSFET RdsON s...
