MBI6662 is a high efficiency, constant current and step-down DC/DC converter. It
is designed to deliver constant current to light up high power LEDs. With the adaptive hysteretic PFM control scheme, MBI6662 can achieve constant frequency operation under common anode connection. The output current of MBI6662 can be set by an external resistor, and LED brightness can be controlled via a pulse width modulation (PWM) signal through DIM pin. In addition, the soft-start function limits the inrush current while the
power is turned on. MBI6662 also features under voltage lock out (UVLO), over temperature protection (OTP), and
over current protection (OCP) to ensure system robustness and prevent IC and LEDs from being damaged once any abnormal condition occurs. To ensure system reliability, MBI6662 is equipped with thermal shutdown protection (TSD), which protects IC from overheating by turning off the internal MOSFET. MBI6662 is available in thermal-enhanced DFN-10 and SOP-10 package to handle power dissipation more efficiently.

Littelfuse, Inc.，作為全球電路保護領域的領先企業，今天推出了簡潔、快熔斷型500VAC陶瓷管保險絲，額定電流為1.6A至12.5A。 514系列陶瓷管保險絲在交流電壓500伏特的條件下, 額定中斷電流高達5,000A，是高壓空調和工業系統高壓交流電源端保護的理想選擇。 其完善的設計通過降低溫度高低循環和震盪的影響，提高了可靠性。 其尺寸僅為6.3mm x 32mm，讓電路設計師能夠騰出保護元件所需的電路板空間。
514系列500VAC管狀保險絲
514系列保險絲適合家庭和建筑自動化市場的高能效和高功率應用，包括高壓空調(HVAC)設備和智慧電錶。 工業市場應用包括不斷電供應系統(UPS)、叁相電源和可再生能源。
“514系列的低額定電流結合高分斷能力在如此小尺寸的保險絲中獨一無二。” Littelfuse全球產品經理 Ben Zheng表示， “當用于叁相交流電源等逆變器電路交流輸出或交流電源的短路保護時，514系列保險絲可在極端惡劣的條件下提供完善的過流保護。”
514系列500VAC陶瓷管保險絲具有下列關鍵優勢：
高額定交流電壓以及500V交流電壓條件下5,000A的額定中斷電流使其成為交流工作電壓高達500V、短路電流高達5,000A的不斷電供應系統中交流電路的理想選擇。
額定電流為1.6A至12.5A，可為高壓交流電路提供可靠的過流保護。
小尺寸(6.3mm x 32mm)陶瓷管體可為需要更高能效的電力轉換設備實現更加簡潔的設計。 這款保險絲適合多數商用低功率電源。
廣泛的工作溫度範圍 (-55°C至125°C) 可確保在極端溫度和惡劣環境中發揮可靠的保護功效。
