Bangalore: Texas Instruments Incorporated (TI) announced volume availability of TMS320F28044 and F2809 digital signal controllers. These devices offer 100 MIPS of 32-bit digital signal processing (DSP) performance optimized for industrial applications like digital power management, servo motor control and intelligent sensor control. The F28044 controller allows power system designers to transition to software-controlled, digital power management using a 32-bit processor and is targeted at multi-channel point of load (POL) applications such as telecommunications and networking infrastructure equipment, servers, laptop computers, and industrial equipment. F2809 controllers allow engineers to develop integrated industrial control systems by combining a host of input, output and communications peripherals.
TI’s TMS320C2000 controller platform’s now includes 18 high-performance, 32-bit controllers that combine real-time DSP performance with the peripheral integration, C-language efficiency and ease of use of a microcontroller (MCU). F28044 and F2809 devices feature a 32-bit wide data path for superior performance and mixed 16-/32-bit instruction set for improved code density. These devices also feature a patent-pending pulse width modulator (PWM) with 150 picosecond (ps) resolution. This unprecedented high-resolution pulse width modulation (HRPWM) technology provides 16 bits of accuracy in a 100 KHz control loop and 12 bits at 1.5 MHz.
It is claimed that the TMS320F28044 is single, programmable controller that can manage up to 16 DC/DC converter channels for multi-phase control. Each channel offers 150ps resolution and is based on patented HRPWM technology. The controller's programmability lets designers build intelligence into power supply systems and simultaneously manage sequencing, margining, phase compensation, and transient response of multiple DC/DC converters. DSP performance plus integrated HRPWM technology provides the full digital loop control and output accuracy necessary at switching frequencies over 1MHz.
