描述
RL78/G24 交错式 PFC + LLC 400W 是一款基于 RL78/G24 微控制器的数字电源控制开发与评估套件。RL78/G24 是一款面向实时控制应用的低功耗 16 位 MCU。 通过单颗 MCU 即可同时控制 PFC 级和双通道 LLC 谐振变换器，从而实现高效率、紧凑型的数字电源解决方案。
该参考设计结合了 RL78 的低功耗技术、优化的 PWM（脉宽调制）控制以及灵活的运行模式切换能力，实现了高峰值效率（>95%）、优异的轻负载效率（>90%），以及超低的待机功耗（在 0.15 W 负载时 <0.3 W）。
内置的数字电源控制专用硬件，可实现模拟控制方式难以完成的复杂控制序列和高精度 PWM 控制。 这不仅简化了对各类能效法规的符合过程，还通过降低系统发热量，减少散热需求，从而有效降低整体系统成本。
特性
- 利用 RL78/G24 微控制器内置的数字电源控制专用功能，实现高效率运行，最高效率可达 95%
- 在轻负载条件下仍可保持高效率，超过 90%
- 通过 RL78 的低功耗设计，实现超低待机功耗，0.15 W 负载时 ≤0.3 W
- 借助灵活应用加速器（FAA），实现灵活且高速的数字电源时序控制，同时将 CPU 负载降至最低
- 采用 RL78/G24 实现 PFC 与 LLC 两级电源架构的单芯片集成控制
- 内置过电流保护（OCP）和过电压保护（OVP）功能
- 通过器件通用化实现电源平台标准化设计，有助于降低半导体供应风险
- 支持模型化开发（MBD）环境
- 通过 QE for Lighting & Power 工具，可无缝支持仿真、参数配置及硬件评估
- 兼容多种 RL78 开发环境
