Providing full-lifecycle solutions for digital power.

Wuhan Senmu Leishi Technology Co., Ltd. is a national high-tech enterprise integrating R&D, manufacturing, and sales. The company independently develops PPEC digital power control cores, EasyGo power electronics hardware-in-the-loop simulation products, and high-end digital power supplies, providing full-lifecycle solutions for digital power applications. Senmu Leishi's self-developed PPEC series of digital power control cores fill a domestic gap in this field and have been widely acclaimed since their launch. Following the releases of the "PPEC-86CA3A" phase-shifted full-bridge control chip and the "PPEC-86CA3H" LC series resonant control chip, the company has officially launched the third product in the PPEC series — the "PPEC-86CA3B" LLC resonant converter control chip.

The PPEC-86CA3B is a power control chip specifically designed for LLC resonant converters, providing power supply R&D companies with a stable and reliable high-efficiency isolated DC/DC control solution. The chip inherits the PPEC's code-free programming development advantage, lowering the barrier to power supply development and shortening R&D cycles.
