TMS320C6711B DSPs供電系統(tǒng)設(shè)計
本文共5頁 3549字
Abstract: This paper describes a low-cost and efficient power solution for TMS320C6711B DSPs applications. The whole system, which is powered by a single 5V power, supplies steady core voltage (1.8V) and I/O voltage (3.3V) with high-efficiency synchronous step-down dc/dc converter TPS54314 and TPS54316, presents a power supply sequencing solution for dual supply voltage DSPs and includes a supervisor on the power supplies and reset circuit in order to make the system more stable and efficient.
Keywords: synchronous PWM, supply sequencing, power supervisor, reset circuit
摘要：本文提出了一種經(jīng)濟、有效的設(shè)計方法來給TI公司的TMS320C6711B數(shù)字信號處理器供電。整個供電系統(tǒng)采用單一的5V電源供電，用高效率的同步電壓轉(zhuǎn)換芯片TPS54314和TPS54316芯片分別產(chǎn)生TMS320C6711B DSPs的內(nèi)核電壓（1.8V）和周邊I/O接口電壓(3.3V)，同時巧妙地解決了兩種供電的順序問題，并增設(shè)了電源監(jiān)控和復位電路，確保供電系統(tǒng)穩(wěn)定、高效地工作。
關(guān)鍵詞：同步脈寬調(diào)制，供電順序, 電源監(jiān)控，復位電路。
