Compatible POL solution for low current applications launched
18 October 2006
Power Electronics / Power Management
Power-One and Micrel have announced availability of a Z-One compatible solution for low-current applications. The solution is based on Micrel's MIC68000 family of linear regulators that are now interoperable with Z-One Point of Load converters (POLs) and ZM7300 digital power managers.
According to the companies, by combining the ZM7300's ability to control analog devices and the advanced power management capabilities of MIC68200, Micrel's first LDO in this family, the companies have created a true open architecture-solution that allows customers to:
* Manage sequencing of multiple outputs with delays that are programmable via the industry standard I²C bus.
* Provide closed loop turn-on and turn-off tracking between Z-One POL converters and the MIC68200 linear regulators with user-programmable slew rates.
* Implement event-based cascading of multiple outputs.
* Generate the system reset signal with programmable delay.
* Execute elaborate fault management and interrupt schemes to offer users a higher degree of system control and flexibility.
Micrel's MIC68200 is a 2 A low dropout regulator, which operates from a wide input range of 1,65 V to 5,5 V and is designed specifically for powering demanding loads in networking, telecom, and computing applications.
Noted Ralf Muenster, Micrel's director of marketing for power products: "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 both money and development time, as it combines the low cost of linear regulators with programmability and the performance of Z-One POLs."
