ＩＲ公司推出的ＩＲ４００７芯片是一种将电压、电流控制与ＭＯＳＦＥＴ集成在一起的开关模式电源集成电路。该芯片具有２００Ｖ的ＭＯＳＦＥＴ开关电源和０４Ω的Ｒｄｓ(ｏｎ）,因而可提供高效的功率转换,减少损耗,采用ＴＯ-２６２（５脚)封装。ＩＲ４００７有两种工作模式:准
IR’s IR4007 chip is a switch-mode power IC that integrates voltage and current control with the MOSFET. The chip features a 200V MOSFET switching power supply and a 04Ω Rds (on) to provide efficient power conversion with reduced losses in a TO-262 (5-pin) package. IR4007 has two modes of operation: accurate
