EP5348UI-E is an evaluation board for EP5348UI, 400mA point of load DC to DC buck converter with integrated inductor, delivers the optimal trade off between footprint and efficiency. It is a perfect alternative to replace less efficient LDOs in space constrained applications that require improved efficiency. The 0.9mm profile and small footprint, enables the use of this part where space is at a premium. A complete power system on a chip (PowerSoC), the EP5348UI integrates power switches, inductor, gate drive, controller and compensation in a tiny 2.0mm x 1.75mm x 0.9mm, 14uQFN package, greatly simplifying the design process. This product is an excellent choice for any application where poor LDO efficiency creates thermal and battery life challenges that could jeopardize meeting Energy Start requirements.
● Integrated inductor technology
● High efficiency up to 90%
● Low Output Ripple
● Fast transient response
● External output voltage programming
● 2.5V to 5.5V input range
● Short circuit and over current protection
● UVLO and thermal protection
●Be mindful of the polarity. Even though the evaluation board comes with reverse polarity protection diodes, it is rarely a good idea to reverse the input polarity.
