UCD3040 具有 4 个反馈环路和 8 个 DPWM 输出的完全可编程的数字功率控制器
UCD3040 描述
The UCD30xx devices are members of a family of digital PWM controllers from Texas Instruments providing a single-chip control solution for digital power-conversion applications. These devices allow digital control implementation of a high-performance, high-frequency power supply with flexible configuration of parameters, supervisory, monitoring, and communication functions.
The UCD30xx are fully programmable solutions that are configurable to support a wide range of isolated and non-isolated topologies in single- or multiphase configurations. Some examples include interleaved PFC, isolated forward, half-bridge, phase-shifted full bridge, active clamp, and resonant LLC.
At the core of the UCD30xx controllers are the digital control-loop peripherals, also known as Fusion Digital Power peripherals (FDPP).
