Digital-DCTM Ease of Use
Zilker Labs developed its innovative Digital-DC ICs to be easy to implement. To make complicated digital power design easy for its customers, Zilker Labs created highly integrated solutions that are easily configurable through simple hardware settings or via the SMBus, avoiding the complicated programming step required by many digital solutions. Zilker Labs also offers a number of design tools to assist its customers' design processes.
High Integration
|
|
Digital-DC ICs combine digital power conversion with power management logic in a single tiny package, reducing required component count by up to 60%. This not only saves board space and cost and simplifies the design process, but it also creates a better-performing, more robust system.
Shown at left is a complete 10A power conversion circuit with tracking, sequencing, margining, and power monitoring capabilities that requires only 0.27 in2 (1.7 cm2). Visit our design gallery for more examples of Digital-DC based applications.

Simple Configurability
Digital-DC ICs can be easily configured with simple pin settings, avoiding the complicated programming step required by alternative solutions. This dramatically eases the design process, and can help the customer avoid assigning a software team to develop complicated code for the digital power supply, resulting in significant time-to-market acceleration. The diagrams below show three different ways for configuring the output voltage on Digital-DC ICs.
Nearly all functions can be configured using these simple methods, including output voltage, switching frequency, soft-start delay/ramp times, UVLO threshold, current limit threshold, sequencing/tracking modes, margining, SMBus address selection and loop compensation.
