22 / 50 page  LTC9101-1/ LTC9102/LTC9103 22 Rev. 0 For more information www.analog.com DEVICE CONFIGURATION An LTC9101-1 can control between one and four LTC9102/LTC9103. Each LTC9102 controls 12 power channels while each LTC9103 controls 8 channels. Thus, each LTC9101-1 can control up to 48 power channels configured in either 2-pair or 4-pair mode. Large port count switch implementation may require a mix of 2-pair (25.5W) ports and 4-pair (up to 71.3W) ports. LTC9101-1 channels may be configured in an arbitrary combination of 2-pair or 4-pair quads by storing a cus- tom configuration package. See Stored Configurations for details. As described later in Bus Addressing, each group of four ports occupies a single I2C address, regardless of 2-pair (2P) or 4-pair (4P) configuration. Using the CFG pins and a default configuration package, a LTC9101-1 can control either all 2-pair ports or can control all 4-pair ports (see Table 4). Table 4.
