ISL6558IRZ-TK

Multi-Purpose Precision Multi-Phase PWM Controller With Optional Active Voltage  Positioning

开关控制器 2-4 PHS PWM CNTRLR NO DAC 20L 5X5 MLFP

The ISL6558IRZ-TK ISL6558 is a multi-phase PWM controller, which in  combination with the HIP6601B, HIP6602B, HIP6603B, or  ISL6605 companion gate drivers form a complete solution  for high-current, high slew-rate applications. The ISL6558  regulates output voltage, balances load currents and  provides protective functions for two to four synchronous  rectified buck converter channels.
