Description
AI
The UCD3020A device is a digital PWM controllers from Texas Instruments providing a single-chip control solution for digital power-conversion applications. This device allows digital control implementation of a high-performance, high-frequency power supply with flexible configuration of parameters, supervisory, monitoring, and communication functions.
The UCD3020A is a fully programmable solution that is 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 UCD3020A controller is the digital control-loop peripherals, also known as Fusion Digital Power peripherals (FDPP). Each FDPP implements a high-speed digital control loop consisting of a dedicated error analog-to-digital converter (EADC), a three-pole and three-zero (3p,3z) digital compensator, and two DPWM outputs with 250-ps pulse-width resolution. The device also contains a 12-bit, 200-ksps general-purpose ADC with up to 9 channels, timers, interrupt controls, and communications ports such as PMBus, SCI, and SPI. The device is based on a 32-bit ARM7 RISC CPU that performs real-time monitoring, configures peripherals, and manages communications. The CPU executes its program out of programmable flash memory as well as ROM.
The UCD3020A is supported by Texas Instruments' Code Composer Studio software development environment.
