EP53A8LQI Description

Short technical summary and product information.

The Intel EP53A8LQI is a non-isolated Point-of-Load (PoL) DC-DC converter module from the Enpirion PowerSoC series. It integrates the inductor, MOSFETs, and compensation in a compact 3.0mm x 3.0mm x 1.1mm 16-pin QFN package, enabling a total solution footprint of approximately 21mm². This device operates with an input voltage range of 2.4V to 5.5V and provides a continuous output current of 1A. The output voltage can be set between 0.6V and VIN-0.5V via a 3-pin VID interface, supporting dynamic voltage scaling.

 

Key electrical characteristics include a typical efficiency of 94% and a 5MHz switching frequency, which allows the use of small external components and low output ripple. The module includes protection features such as overcurrent protection (OCP), overtemperature protection (OTP), short-circuit protection (SCP), and under-voltage lockout (UVLO). Control is via an enable pin with active high logic.

 

The device is designed for commercial ITE applications and operates over an ambient temperature range of -40°C to +85°C. It is offered in a surface-mount 16-QFN (3x3) package. The EP53A8LQI is RoHS3 compliant and lead-free compatible. An alternate variant, EP53A8HQI, is available without support for an external voltage divider.
