ZL8800 Description
DATASHEET ZL8800 Dual Channel/Dual Phase PMBus ChargeMode Control DC/DC Digital Controller FN7558 Rev.6.00 Nov 8, 2017 The ZL8800 is a dual output or dual phase digital DC/DC controller. Each output can operate independently or be used together in a dual phase configuration for high current applications. The ZL8800 supports a wide range of output voltages (0.54V to 5.5V) operating from input voltages as low as 4.5V...
