TMS320C28345 (ACTIVE)

Delfino Microcontroller

Description

The TMS320C2834x (C2834x) Delfino™ microcontroller (MCU) devices build on TI's existing F2833x high-performance floating-point microcontrollers. The C2834x delivers up to 300 MHz of floating-point performance, and has up to 516KB of on-chip RAM. Designed for real-time control applications, the C2834x is based on the C28x™ core, making it code-compatible with all C28x microcontrollers. The onchip peripherals and low-latency core make the C2834x an excellent solution for performance-hungry realtime control applications.

TPS62404   Dual, 400mA and 600mA, 2.25MHz Step-Down Converter with 1-Wire Interface in QFN   CONVERTER (INTEGRATED SWITCH) - STEP-DOWN (BUCK) CONVERTER    The TPS62404 dual-output DC/DC converter uses a small number of external components and needs only 220 mm2 PCB space, making it ideal for building a small, efficient and cost-effective power solution for TMS320F28332/3/5 controllers operating from a 5-V bus supply. With built-in sequencing, the TPS62404 ramps up both output voltages, with the lower core voltage reaching its final value first.
