Description
L6728D is a single-phase step-down controller
with integrated high-current drivers that provides
complete control logic and protection to simplify
the design of general DC-DC converters by using
a compact DFN10 package.
Device flexibility allows the management of
conversions with power input (VIN) as low as
1.5 V, and device supply voltage ranging from 5 V
to 12 V.
The L6728D provides a simple control loop with
voltage mode EA. The integrated 0.8 V reference
allows output voltages regulation with ±0.8%
accuracy over line and temperature variations.
The oscillator is internally fixed to 300 kHz.
The L6728D provides programmable dual level
overcurrent protection, as well as overvoltage and
undervoltage protection. Current information is
monitored across the low-side MOSFET RDS(on),
eliminating the need for expensive and space-
consuming sense resistors.
A PGOOD output easily provides real-time
information on output voltage status, through the
VSEN dedicated output monitor.
