This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
DESCRIPTION
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). Each FDPP implements a high-speed digital control loop consisting of a dedicated
error analog-to-digital converter (EADC), a three-pole/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 15 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 UCD30xx is supported by Texas Instruments' Code Composer Studio™ software development environment.
