UCC28180 的說明

The UCC28180 is a flexible and easy-to-use, 8-pin, active Power-Factor Correction (PFC) controller that operates under Continuous Conduction Mode (CCM) to achieve high Power Factor, low current distortion and excellent voltage regulation of boost pre-regulators in AC - DC front-ends. The controller is suitable for universal AC input systems operating in 100-W to few-kW range with the switching frequency programmable between 18 kHz to 250 kHz, to conveniently support both power MOSFET and IGBT switches. An integrated 1.5-A and 2-A (SRC-SNK) peak gate drive output, clamped internally at 15.2 V (typical), enables fast turn-on, turn-off, and easy management of the external power switch without the need for buffer circuits.

Low-distortion wave shaping of the input current using average current mode control is achieved without input line sensing, reducing the external component count. In addition, the controller features reduced current sense thresholds to facilitate the use of small-value shunt resistors for reduced power dissipation, especially important in high-power systems. To enable low current distortion, the controller also features trimmed internal current loop regulation circuits for eliminating associated inaccuracies.

Simple external networks allow for flexible compensation of the current and voltage control loops. In addition, UCC28180 offers an enhanced dynamic response circuit that is based on the voltage feedback signal to deliver improved response under fast load transients, both for output overvoltage and undervoltage conditions. An unique VCOMP discharge circuit provided in UCC28180 is activated whenever the voltage feedback signal exceeds VOVP_L thus allowing a chance for the control loop to stabilize quickly and avoid encountering the overvoltage protection function when PWM shutoff can often cause audible noise. Controlled soft start gradually regulates the input current during start-up and reduces stress on the power switches. Numerous system-level protection features available in the controller include VCC UVLO, peak current limit, soft overcurrent, output open-loop detection, output overvoltage protection and open-pin detection (VISNS). A trimmed internal reference provides accurate protection thresholds and regulation set-point. The user can control low-power standby mode by pulling the VSENSE pin below 0.82 V.

包裝類型選項

您可依零件數量選擇不同包裝類型選項,包含完整捲盤、客製化捲盤、剪切捲帶、承載管或盤。

客製化捲盤是從一個捲盤上剪切下來的連續剪切捲帶,以維持批次和日期代碼可追溯性,依要求剪切至確切數量。依照業界標準,銅墊片會在剪切捲帶兩側連接 18 英吋前後導帶,以直接送至自動組裝機器。針對客製化捲盤訂單,TI 將酌收捲帶封裝費用。

剪切捲帶是從捲盤剪切下來的一段捲帶。TI 可能使用多條剪切捲帶或承載盒,以滿足訂單要求數量。

TI 常以盒裝或管裝、盤裝方式運送承載管裝置,視現有庫存而定。所有捲帶、管或樣本盒之封裝,皆符合公司內部靜電放電與防潮保護包裝要求。
