Function Overview

EN5312QI is a complete DCDC converter solution, only two low -cost MLCC capacitors. The MOSFET switch, PWM controller, gate driver, compensation and inductance are integrated in tiny 5mm x 4mm x 1.1mm packaging. While maintaining high -efficiency, low ripples and high performance, it provides as small area as possible. The converter uses voltage mode control to provide the simplest implementation and high noise resistance. The operating frequency of this device is very high. The high -push frequency allows the width to control the loop bandwidth to provide excellent transient performance. High -open frequency makes this very small component make this unprecedented integrated level possible.

ENPIRION's proprietary power MOSFET technology provides very low switching loss at 4MHz and higher frequencies, allowing very small internal components and very wide control ring bandwidth. Unique magnetic design allows integrated sensors to a very low 1.1 mm package. The integration of the inductors actually eliminates the design/layout of the switch -type DCDC converter. All these make it easier and faster to integrate into various applications to meet the requirements of higher electromagnetic interference.

The output voltage is selected from seven preset values through a three -pin video voltage selection solution. The external compressor option allows any voltage within the range of 0.6V to Vin0.6V. This reduces the number of components that must be qualified and the burden of inventory. The video tube foot can be switched at any time to achieve non -fault -free dynamic electrococcilities.

The protection function includes the underwriter lock (UVLO), overcurrent protection (OCP), short -circuit protection and heat overload protection.

Integrated inductance

Enpirion launched the world's first product series with integrated sensors. Using internal sensors can locate noise related to output circuit current. The inherent shielding and compact structure of integrated inductance reduces the radiation noise of coupling to the trajectory of the circuit board. In addition, the packaging layout is optimized to reduce the circuit length of the AC wave current of the main source of the DCDC converter radiation. The integrated electromotone significantly reduces the parasitic effect, which may damage the stability of the ring road and make the layout very simple.
