Power-One Inc. and Micrel Inc. jointly announced a Z-One-compatible solution for low-current applications. The solution is based on Micrel's MIC68000 family of linear regulators now interoperable with Power One's Z-One point-of-load (POL) converters and ZM7300 digital power managers.

By combining ZM7300's ability to control analog devices and MIC68200's advanced power management capabilities, the two companies have created a true open-architecture solution to manage sequencing of multiple outputs with delays that are programmable via the industry standard I?C bus.

Moreover, the solution offers closed loop turn-on and turn-off tracking between Z-One POL converters and MIC68200 linear regulators with user-programmable slew rates. It also implements event-based cascading of multiple outputs and generates the system reset signal with programmable delay.

The MIC68200 is a 2A-low dropout regulator operating on 1.65-5.5V input range. It is specifically designed for powering demanding loads in networking, telecom and computing applications. The device is currently available and volume pricing starts at $1.63 for 1,000-unit quantities.

"This is a result of synergy between Power-One's know-how in digital power management and Micrel's expertise in high performance linear regulators," said William T. Yeates, Power-One CEO. "The solution is cost-effective and addresses customers' needs for advanced power management at sub-2A current levels. This substantially increases the serviceable market for Z-One technology."

"Micrel's new LDO integrates seamlessly with Z-One Digital Power Architecture," said Ralf Muenster, director of marketing for power products at Micrel. "The MIC68200 eliminates the need to buy higher-priced, higher-current analog POL converters to implement advanced power management features such as sequential tracking or ratiometric power up and power down. It saves customers both money and development time, as it combines the low cost of linear regulators with programmability and the performance of Z-One POLs."
