FN7360.5
Monolithic 4A 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 Ld HTSSOP package and is
specified for operation over the -40°C to +85°C temperature
range.
