EP5358LUA/HUA 600mA PowerSoC
Voltage Mode Synchronous
PWM Buck with Integrated Inductor
Description
The EP5358LUA and EP5358HUA are 600mA
PowerSoCs that are AEC-Q100 qualified for
automotive applications. The EP5358xUA (x = L or H)
is rated for up to 600mA of continuous output current.
The EP5358xUA integrates MOSFET switches,
control, compensation, and the magnetics in an
advanced 2.5mm x 2.25mm micro-QFN Package.
Integrated magnetics enables a tiny solution footprint,
low output ripple, low part-count, and high reliability,
while maintaining high efficiency. The complete
solution can be implemented in as little as 14mm².
The EP5358xUA uses a 3-pin VID to easily select the
output voltage setting. Output voltage settings are
available in 2 optimized ranges providing coverage
for typical V_OUT settings.
The VID pins can be changed on the fly for fast
dynamic voltage scaling. EP5358LUA further has the
option to use an external voltage divider.
The EP5358xUA is a perfect solution for noise
sensitive and space constrained applications that
require high efficiency.
