Overview: DATASHEET ZL8802
Dual Channel/Dual Phase PMBus ChargeMode Control DC/DC Digital Controller FN8760 Rev.3.00 Nov 8, 2017 The ZL8802 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 supporting 2-, 4-, 6-, and 8-phase operation with up to four ZL8802 controllers.
The ZL8802 supports a wide range of output voltages (0.54V to 5.5V) operating from input voltages as low as 4.5V up to 14V.
With the fully digital ChargeMode control, the ZL8802 will respond to a transient load step within a single switching cycle. This unique compensation-free modulation technique allows designs to meet transient specifications with minimum output capacitance, thus saving cost and board space.
The proprietary single-wire Digital-DC™ (DDC) serial bus enables the ZL8802 to communicate between other Intersil digital power ICs. By using the DDC, the ZL8802 achieves complex functions such as inter-IC phase current balancing, sequencing, and fault spreading. This eliminates complicated power supply managers with numerous external discrete components.
