Austin, TexasZilker Labs Inc. introduced a pair of adaptive DC-DC power controllers that is intended to maximize efficiency in power-constrained applications, particularly in the embedded computing, storage and telecom/datacom sectors.
The ZL2006 and ZL2004 are part of the company's Digital-DC technology product line. The ZL2006 and ZL2004 include proprietary algorithms that dynamically optimize the efficiency as operating conditions change, with no interaction or additional components required.
According to Zilker, the algorithms result in a full-load efficiency improvement up to 3 percent and a light-load-efficiency increase greater than 15 percent in typical applications, reducing peak power dissipation by up to 20 percent.
The ZL2006 is a universal power building block that can be used alone or connected in parallel to address a wide variety of load currents with a single IC. Additionally, both the ZL2006 and ZL2004 support accurate current sharing between paralleled ICs through a proprietary single-wire Digital-DC bus. This high-speed bidirectional bus provides a simple communications channel over which multiple Digital-DC devices can share current information to provide N+1 redundant operation in mission-critical applications. If one device is subjected to a fault condition, the current sharing master duties can be transparently passed to another IC to provide continuous operation.
The ZL2006 integrates 3A MOSFET drivers that can support loads in excess of 40A with no external driver needed. The ZL2004 is intended to interface with external driver/MOSFET ICs and power train modules.
The ZL2006 is available in a 6 x 6 mm 36-lead QFN package and the ZL2004 is available in a 5 x 5 mm 32-lead QFN package.
Pricing: Starts at $2.95 in quantities of 1,000.
Availability: General sampling.
