Zilker Labs introduces a single-chip 3 Amp power conversion solution that integrates full digital power management capabilities. The ZL2105 extends Zilker Labs' innovative Digital-DC technology into lower power applications and combines a synchronous step-down converter including synchronous power MOSFETs with key power management functionality in a tiny 6 x 6 mm package. A ZL2105 circuit with full digital power management capabilities requires less than two square centimeters of board space, representing size and component count reductions of up to 50 percent. Like all Digital-DC ICs, the ZL2105 is designed to be a digital building block that can be seamlessly combined with other Digital-DC devices to provide a comprehensive solution for board-mounted power management and conversion.
"The ZL2105 is a key addition to our Digital-DC product family and advances our goal of making advanced power design simple. The ZL2105 combines the digital power management capabilities, simple configurability and high efficiency of our existing ZL2005 into a part that is ideal for lower power applications," said Jim Templeton, Zilker Labs' vice president of marketing. "Customers can combine multiple Digital-DC devices on a given PCB and easily configure the parts to simplify a complicated power design. Ours are the only solutions to offer this 'plug and play' experience for board-level power."
Zilker Labs' Digital-DC products are fully configurable with simple pin-strap connections, resistor selection or via the device's on-board serial port using the industry-standard PMBus (Power Management Bus) command set. The single-chip Digital-DC products provide the configurability, control and monitoring capabilities of digital power technology without compromising efficiency. Additionally, they eliminate the requirement for user programming. To combine multiple Digital-DC ICs in a given application, the designer simply configures each IC via pin-strap selection and connects the serial bus (SMBus) of each device. The devices then communicate with each other via the SMBus and can operate independent of a host controller. The devices can be monitored and controlled individually or as a system.
"By extending their Digital-DC technology into lower power applications, Zilker Labs allows system designers to create a simple, easily implemented, and intelligent power system across a wider range of end products," said principal analyst Jim McGregor of In-Stat.
Zilker Labs began sampling the ZL2105 in July to select customers. The ZL2105 is available in a 6 x 6 mm 36-lead QFN package. Pricing starts at US$2.80 in quantities of 1,000. An evaluation kit, the ZL2105EV1, is also available.
