Regulator Balance Controller - Semtech Corporation

The EZ1900 is a high performance positive load cur- rent balancer designed for use in applications utiliz- ing 2 Regulators in parallel to achieve equal current sharing or identical current for each load. The regula- tor balance controller allows a flexible motherboard design to be made to cope with different processor configurations. The controller reads a Logic level up- grade signal (denoted VCC2DET on the Intel P55C; sim- ilar on AMD, Cyrix and PowerPC microprocessors) to control the output voltage of two linear low dropout voltage Regulators to the CPU core and I/O planes. In single-voltage plane configurations (VCC2DET floating), both Regulators are set to the same output voltage (usually 3.3 - 3.5V) and are configured in master- slave mode. For split plane processors (VCC2DET low), the outputs of the two Regulators are switched - the core voltage will be set to a nominal 2.5V while the I/O voltage will remain at 3.3V. The actual output voltages CAN be adjusted by means of resistors. The EZ1900 programmable current balancer is available in the popular SO-8 surface mount package. By Semtech Corporation
