APM80900 & APM80904 ClearPower模組
Allegro MicroSystems
汽車級、低EMI、1.5 A PWM可調光 同步降壓LED模組
Automotive-Grade, Low-EMI, 1.5 A PWM Dimmable Synchronous Buck LED Module
Allegro MicroSystems的ClearPower模組產品系列,採用“系統級封裝”方法,提供了設計人員長期以來一直在尋找的答案。ClearPower模組將高性能電源開關或LED驅動器的所有主要元件封裝在一個緊湊的封裝內,大大簡化了完整電源解決方案的設計任務。
Allegro最近開發的ClearPower模組APM80900,就是用於LED照明應用得例子。
功率感測器、電容器開關及高級開關穩壓器IC共同封裝在尺寸僅為4x6x2mm的外殼中,同時採用基板佈線技術將各子組件連接在一起,並與外界相連。
透過將這些關鍵的功率級元件,集中放置在緊密的範圍內,導致EMI的高電流開關路徑減少了10倍。此外,直接透過整合和創新的IC設計,整體尺寸可減少高達70%常規解決方案。
Allegro MicroSystems的ClearPower模組,採用MIS(模擬基板互連)可佈線引線框封裝,具有傳統QFN解決方案的外觀和感覺。將此技術與行業標準QFN封裝與可潤濕側面相結合,可確保汽車在最苛刻的工作溫度下可靠運行。
雖然使用電源模組開發可透過EMI限制的可行電源解決方案,任務就變得容易得多,但實現高性能需要對模組本身的設計採用整體方法。這項工作涉及結合IC設計、封裝技術和無源元件整合,以實現所需的EMI、熱性能和尺寸。
The APM80900 and APM80904 are complete synchronous buck switching regulator ClearPower modules that provide constant current for driving high-power LEDs. They integrate both high-side and low-side switches along with the inductor, the input capacitor, and the boot capacitor. Current regulation is achieved on a cycle-by-cycle methodology that utilizes varying the on-time.
