The chip is a new fully integrated DC-DC converter featuring on-chip orthogonally placed 8-shaped stacked transformers for miniaturized power delivery. It achieves power conversion efficiency up to 74.5% and peak power density of 3.2W/mm^2 delivering 23uW-0.3W output power. The proposed on-chip transformer design minimizes the magnetic field intensity outside of its borders, mitigating issues such as parasitic coupling, local oscillator pulling and EMI, demonstrating a measured 27dB reduced magnetic interference.

This chip was manufactured with generous sponsorship by HiSilicon through the Europractice-IC service.
During initial planning stage, the die area was reserved for a PLL implementation, later in the project, it was decided to make a second version of the DC DC converter. This caused some confusion as the chip is officially listed as PLL2200 in several documents.
