CHL8228G-11CRT Description
CHL8228G-11CRT is a dual-loop, digital multi-phase buck controller. The CHL8228G-11CRT drives up to 8 phases. It features Input Voltage Management allowing up to 3 input voltages to be monitored to ensure adequate power is delivered to the load. Dynamic voltage control is provided by 4 registers which are programmed through I2C/SMBus/PMBus and then selected using a 2-bit parallel bus for fast access. The CHL8228G-11CRT includes the IREfficiency Shaping Technology to deliver exceptional efficiency at minimum cost across the entire load range.
