The Enpirion® EP53A8HQI/LQI 1A, 5 MHz DC-DC step-down (buck) converter with integrated inductor represents a revolution in the area of low-power switching converters. The total solution footprint is as small as 21 mm2, without compromising efficiency.
A complete power system-on-a-chip (PowerSoC), the EP53A8HQI/LQI integrates power switches, inductor, gate drive, controller, and compensation in a tiny 3 mm x 3 mm package. The 1.1 mm profile and small footprint enable the use of this part where space is at a premium. In addition, this point-of-load solution requires only two tiny multilayer ceramic capacitors (MLCC), reducing the overall solution cost and simplifying the supply chain. The EP53A8LQI further has the option to use an external voltage divider.
The EP53A8HQI/LQI utilizes a 3-pin VID output voltage selector that allows the designer to choose one of seven pre-defined output voltage levels, or an external voltage divider can be employed to set the output voltage.
This power management IC is an excellent choice for low-power applications that require a small solution footprint, high efficiency, exceptional thermal performance, low noise, high reliability, and ease of use.
