Rev.3.00
Nov 8, 2017 Dual Channel/Dual Phase PMBus ChargeMode Control DC/DC Digital Controller
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. Features 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. 1% output voltage accuracy over line, load, and temperature 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. Unique compensation-free design – always stable Output voltage range: 0.54V to 5.5V Input voltage range: 4.5V to 14V ChargeMode control achieves fast transient response,
reduced output capacitance, and provides output stability
without compensation. 2-channel output, 2-, 4-, 6-, or 8-phase output with two,
three, or four devices Switching frequency range 200kHz to 1.33MHz The proprietary single-wire Digital-DCв„ў (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 …
