Voltage-Mode Control当误差电压直接通过脉冲宽度调制器驱动占空比,这个被称为直接占空比控制或电压模式控制。电压模式控制中,误差电压与锯齿波相比较,得到占空比。 在电压模式控制下,如果出现过流或者短路故…
講師先針對 Buck regulator topology 作簡單的介紹,接下來針對不同的control mode也有詳細的說明,最後再針對 TI 在 Notebook DC/DC 的相關產品進行說明。講師針對電源供應的理論與常見的筆電系統設計範例都有深入簡出的分析,是在進行筆電設計時相當實用的培訓影片。
摘要: Unitrode IC Corporation has, since its inception, been active in the development of leading-edge control circuits to implement state-of-the-art progressions in power supply technology. Over the years many new products have been introduced to allow designers to readily...
Application Note ANP 15 Voltage Mode Control: The Modulator in Continuous Current Mode (CCM) of operation There are three main components in the control loop of a voltage mode DC to DC converter. The three stages are the output stage consisting of the output filter, the modulator gain, and...

A strategy for realizing a switching-mode instrumentation power supply (SMIPS) by zero-voltage switching pulse-width modulation (ZVS-PWM) technique is presented. The proposed ZVS-PWM SMIPS is capable of constant-voltage (CV) and constant-current (CC) control with adjustable output voltage/current...
USART3 mode and configuration settings Configure the USART3 for Host-Target communication. GPIO configuration settings BUCKBOOST P2 DRIVE and BUCKBOOST N2 DRIVE are not used in the Buck-only configuration. However, the BUCKBOOST P2 DRIVE must be High to support the Buck-only configuration. BUCKBO...
