  1. MOSFET for MP3 Player

  2. Summary • MP3 Player Trend and Overview • MP3 Player - Application Type • MP3 Player - MOSFET Selections

  3. MP3 Player Trend and Overview • MP3 ??? • 數位音訊壓縮技術&公開標準 • 可壓縮PCM data 到10:1or更高壓縮比 • 運用人體聽覺系統之遮蔽效應 • MP3(MPEG Layer 3)

  4. MP3 Player Trend and Overview • 2004 MP3 發展- 1 • 多功能整合為一機(功能型MP3 可聽可看) • 造型多變&外觀新穎(個性化流行裝飾&產品形式/消費族群區隔) • 存儲容量提高(Flash(128MB→1GB) /HDD(1.5GB→40GB)) • 存儲型態多元化(市場以Flash為主(價格因素)) Flash-based(60%) / HDD based / CD based • 低耗能(高整合化晶片 D類放大器&電源管理模式:耗電量 降低 /撥放使用時間增長) • 傳輸介面演進(USB /USB OTG(On The Go)/未來趨勢-無線傳輸Wireless(bluetooth))

  5. MP3 Player Trend and Overview • 2004 MP3 發展 - 2 • 多功能整合 • LCD / 彩色螢幕OLED • APDPCM / MP3語音錄音 • FM撥放錄音 • 支援其他壓縮格式(WMA ACC OGG…) • EQ mode • 語言學習 • 多國語言顯示 • 遊戲 /照片欣賞 /電子書閱讀 • 運動型: 慢步計 /熱量計 /運動量計

  6. MP3 Player Trend and Overview • 2004 MP3 發展 - 3 • MP3 產品需求 • 多功能設計 • 儲存容量大 • 體積小 • 高音質 • 低耗電量 • 外型設計多樣化(headphone/Player+USB OTG(Flash/HDD/CD) /錶/Desktop &車用音響…) • 人性化設計介面 • 低價位 • 商品附屬功能含MP3(手機/PDAs/耳機/鐘錶/IA/HiFi…)

  7. MP3 Player – Application Type • OLED應用 • OLED(有機發光二極體)的電源規格需求: 一般小尺寸的OLED 的電源,需一組正電壓( Vdd)輸出,與一組負電壓( Vss)輸入,而電源的架構,可分為 1.數位相機架構 ( Vdd電壓範圍為3~6V,而Vss電壓範圍為-7~-10V) 2.手機架構 ( Vdd電壓範圍大約為2.5V ; Vss電壓範圍為-7~-10V) 而這兩種產品的輸入電源,通常為一顆鋰電池 (電壓範圍大約為3~4.2V)。
