The ZL8101 is a digital PWM controller with auto

compensation that is designed to work with either the ZL1505

MOSFET driver IC, ISL6611 Phase Doubler IC, or DrMOS type

devices. Current sharing allows multiple devices to be

connected in parallel to source loads with very high current

demands. Adaptive performance optimization algorithms

improve power conversion efficiency across the entire load

range. Zilker Labs Digital-DC™ technology enables a blend of

power conversion performance and power management

features.

The ZL8101 is designed to be a flexible building block for DC

power and can be easily adapted to designs ranging from a

single-phase power supply operating from a 4.5V input to a

multi-phase supply operating from a 12V input. The ZL8101

eliminates the need for complicated power supply managers

as well as numerous external discrete components.

Most operating features can be configured by simple

pin-strap/resistor selection or through the SMBus™ serial

interface. The ZL8101 uses the PMBus™ protocol for

communication with a host controller and the Digital-DC bus

for communication between other Zilker Labs devices.
