QUICK TAKE:
Zilker Labs has introduced the industry's only single-chip 3A power conversion IC that integrates full digital power management capabilities. ZILKER LABS, Austin, TX. (512) 382-8300.
More Info:
Requiring less than two square centimeters of board space, the ZL2105 combines a synchronous step-down converter, including synchronous power MOSFETs, with key power management functionality. The part can provide an output voltage from 0.6V to 5.5V from an input voltage between 4.5V and 14V. Like all of the company's 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.
WHY IS THIS IMPORTANT?
The ZL2105 combines the digital power management capabilities, simple configurability and high efficiency of the company's existing ZL2005, yet can be used for lower power applications.
MORE ABOUT DIGITAL-DC
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.
PRICING AND AVAILABILITY
Available in a 6 mm x 6 mm 36-lead QFN package, the ZL2105 began sampling to select customers in July. Pricing starts at $2.80 each/1,000. An evaluation kit, the ZL2105EV1, is also available.
