EL7554
Monolithic 4 Amp DC-DC Step-Down
Regulator
The EL7554 is a full-feature synchronous 4A step-down
regulator capable of up to 96% efficiency. This device
operates from 3V to 6V V
IN
input supply. With internal
CMOS power FETs, the device can operate at up to 100%
duty ratio, allowing for output voltage range from 0.8V up to
nearly V
IN
.The adjustable high switching frequency of up to
1MHz enables the use of small components, making the
whole converter occupy less than 0.58 square inch with
components on one side of the PCB. The EL7554 operates
at constant frequency PWM mode, making external
synchronization possible. The EL7554 features soft-start
and full start-up control, which eliminates the in-rush current
and enables users to control the start-up of multiple
converters to any configuration with ease. The EL7554 also
offers a ±5% voltage margining capability that allows raising
and lowering of the supplies derived from the EL7554 to
validate the performance and reliability of system cards
quickly and easily during manufacturing testing. A junction
temperature indicator conveniently monitors the silicon die
temperature, saving designers time in the tedious thermal
characterization.
An easy-to-use simulation tool is available for
download
and
can be used to modify design parameters such as switching
frequency, voltage ripple, ambient temperature, as well as
view schematics waveforms, efficiency graphs, and
complete BOM with Gerber layout.
The EL7554 is available in a 28-pin HTSSOP package and
is specified for operation over the -40°C to +85°C
temperature range.
