振邦微科技新推出3.7V升5V2A兼容進口MP2359/AH6901一款超小封裝高效率、直流升壓穩壓電路。輸入電壓范圍可由最低2V伏特到最高16伏特，升壓最高可達20V可調，且內部集成極低RDS內阻100豪歐金屬氧化物半導體場效應晶體管的(MOSFET)，可實現高達2A大電流。AH6901應用電路非常簡單，外圍器件極少。振蕩頻率1.2MHZ，效率高達95％，該電路具有短路保護，過熱保護等功能，具有更高的可靠性，安全性！
AH6901采用標準的SOt-23-6無鉛封裝，現以開始大批量供貨。
應用：?
電池供電設備、便攜式DVD、移動電源、通訊設備、數碼產品
機頂盒、3G網絡產品
LCD液晶屏背光電路
ADSL和電纜調制解調器和路由器?
PCI Express插槽供電

Layout Considerations 1. The power traces, consisting of the GND trace, the LX trace and the VCC trace should be kept short, direct and wide. 2. LX、L and D switching node, wide and short trace to reduce EMI. 3. Place CIN near VCC pin as closely as possible to maintain input voltage steady and filter out the pulsing input current. 4. The resistive divider R1and R2 must be connected to FB pin directly as closely as possible. 5. FB is a sensitive node. Please keep it away from switching node, LX. 6. The GND of the IC, CIN and COUT should be connected close together directly to a ground plane.
