功能與IR公司的IR1150相同,性價比遠勝于IR1150.而第二代的產品(ICE1PCS01/02)相比第一代(ICE1PCS01/02)在電流偕波,動態響應好很多.
ICE1PCS01/02和ICE2PCS01/02的對比如下:
To switch to ICE2PCSxx, major changes are in
>>
>>1. the voltage divider resistors at Vsense , due to the internal reference
>>voltage change from 5V to 3V.
>>2. the Vcc supply voltage, due to its operating range change
>>
>>To reduce PCB related noise, the following are possible -
>>
>>1. increase cap up to 6.8nF at Icomp
>>2. add a cap up to 0.1uF at Vsense
