EP5368QI 600mA PowerSoC
Synchronous Buck Regulator
With Integrated Inductor
Description
The EP5368QI is a synchronous buck converter
with integrated Inductor, PWM controller,
MOSFETS, and Compensation providing the
smallest possible solution size. The EP5368QI
requires only two small MLCC capacitors to
make a complete solution. Integration of the
inductor greatly simplifies design, contains noise,
reduces part count, and reduces solution
footprint. Low output ripple ensures compatibility
with RF systems.
The EP5368QI operates at a switching frequency
of 4 MHz, enabling this unprecedented level of
integration and small external components. Type
III voltage mode control is used to provide high
noise immunity and wide control loop bandwidth.
The device can source 600mA of current over
the industrial temperature range and up to
700mA over the commercial temperature range.
The small footprint makes this part ideal for
space constrained applications. Output voltage
is programmed via a 3-pin VID selector providing
seven pre-programmed output voltages along
with an option for external resistor divider.
