Introduction

Traditional flyback architectures can no longer meet the requirements of high switching frequency, high power density, and high efficiency for high-power adapters. As a result, the LLC architecture, better suited for higher power outputs, has been introduced into 100W+ high-power adapters. This effectively improves conversion efficiency, reduces size, enhances portability, and increases product competitiveness.

Additionally, due to the use of large-capacity filter capacitors in rectified switching power supplies, which exhibit capacitive loads, significant high-order harmonics are generated during the charging and discharging processes, causing pollution and interference in the power grid. To address this, engineers have begun incorporating PFC (Power Factor Correction) circuits into switching power supplies. For power supplies exceeding 75-85W, PFC circuits are mandatory to improve the power factor and correct load characteristics.

In response to the current trends of high efficiency and miniaturization in adapters, MPS has introduced a range of PFC+LLC combo controllers to help manufacturers significantly enhance product integration. Recently, ChargerLab identified multiple devices equipped with MPS PFC+LLC controllers. The following article will provide a detailed introduction.

Regarding PFC control, HR1275 can maintain high efficiency from light load to full load and has intelligent valley switching technology and input capacitor current compensation function to reduce noise and improve system efficiency. The LLC control part adopts current mode control, supports precise burst mode entry and exit control, has 600V high-side gate drive capability, and has adaptive dead time adjustment and capacitor mode protection. The chip also has over-temperature, over-current, and over-power protection, supports a maximum operating frequency of 500kHz, and is suitable for high-efficiency power supply design.
