IR 公司的IRAUDPS1是12V系統250W-1000W D類(lèi)音頻功率放大器電源設計方案,采用IR公司的自振蕩柵極驅動(dòng)器IR2085和Direct FETS IRF6648.適用于汽車(chē)電子應用,為D類(lèi)音頻放大器提供+B和-B電源. IRAUDPS1是可升級的設計.本文介紹了IRAUDPS1設計的方框圖, IR2085 模塊電路圖, IRAUPS1主板電路圖以及IRS2085模塊材料清單, IRAUPS1 500W主板材料清單和機械零件材料清單與變壓器電特性參數.

IRAUDPS1
12V System 250W-1000W Scalable Audio Power Supply For Class D Audio Power Amplifiers Using the IR2085 self oscillating gate driver And Direct FETS IRF6648

圖1. IRAUDPS1參考設計外形圖
The IRAUDPS1 reference design is a 12 volts systems Audio Power Supply for automotive applications designed to provide voltage rails (+B and –B) for Class D audio power amplifiers
This reference design demonstrates how to use the IR2085 as PWM and gate driver for a Push-Pull DC to DC converter, along with IR’s Direct FETS IRF6648.
The resulting design uses a compact design with the Direct FETS and provides all the required protections.
IRAUDPS1 is a scalable power output design, and unless otherwise noted, this user’s manual is based on the 500W model
