EP5388QI Datasheet PDF - Enpirion

●The EP5388QI is a synchronous Buck Regulator with integrated inductor, PWM controller, MOSFETS and compensation providing the smallest possible solution size. The EP5388QI 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 EP5388QI operates at a switching frequency of 4MHz, 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.
