The Ultra-Low-Profile EP53X2Q product family is
targeted to applications where board area and
profile are critical. EP53X2Q is a complete power
conversion solution requiring only two low cost
ceramic MLCC caps.
Inductor, MOSFETS,
PWM, and compensation are integrated into a
tiny 5mm x 4mm x 1.1mm QFN package. The
EP53x2Q family is engineered to simplify design
and to minimize layout constraints.
High
switching frequency and internal type III
compensation provides superior transient
response. With a 1.1 mm profile, the EP53x2 is
perfect for space and height limited applications.
A 3-pin VID output voltage select scheme
provides seven pre-programmed output voltages
along with an option for external resistor divider.
Output voltage can be programmed on-the-fly to
provide fast, dynamic voltage scaling.
