Micrel Launches Industry's First LDO Featuring Built-In Sequencing, Tracking and Ramp Control for Low Voltage FPGAs, DSPs and ASICs
SAN JOSE, Calif., Dec. 21 - Micrel Inc., (NASDAQ:MCRL), an industry leader in analog, high bandwidth communications and Ethernet IC solutions, today launched the MIC68200, a 2A LDO regulator designed specifically for powering applications such as FPGA or ASIC core voltages which require high start-up current with lower nominal operating current including Industrial, Telecom, and High-end Consumer (digital TV, LCD/ Plasma TVs, etc.) applications. The MIC68200 is currently available in volume and pricing starts at $1.63 for 1K quantities.
"Micrel's new LDO is the only device on the market that offers a ramp control (RC) pin that provides control over Vin ramp rate," noted Ralf Muenster, Micrel's director of marketing for power products. "The MIC68200 eliminates the need to buy higher-priced, higher-current limited devices to address current overshoot at turn-on. Many systems require complex power up protocols and the MIC68200 enables the designer to implement sequential tracking as well as ratiometric power up and power down. In doing so, it can eliminate the need for more complex power management ICs."
The various power-up and power-down protocols such as sequencing, tracking, and ratiometric tracking can be implemented very easily with the use of very few passive components. The MIC68200 operates from a wide input range of 1.65V to 5.5V, including all of the main supply voltages commonly available today. It is designed to drive digital circuits requiring low voltage at high currents (i.e., PLDs, DSPs, microcontroller, etc.). The MIC68200 incorporates a delay pin (Delay) for control of power on reset output (POR) at turn-on and power-down delay at turn-off. In addition, there is a ramp control pin (RC) for either tracking applications or output voltage slew rate adjustment at turn-on and turn-off. This is crucial in applications where the load is highly capacitive and in-rush currents can cause supply voltages to fail and microprocessors or other complex logic chips to hang up. Multiple MIC68200s can be daisy chained in either tracking or sequencing mode. The MIC68200 is fully protected offering both thermal and current limit protection and reverse current protection. It has a junction temperature range of -40 degrees C to +125 degrees C and is available in fixed voltages of 1.8V, 1.5V, 1.2V and 1.0V. There is also an adjustable option. The MIC68200 is offered in the tiny 10-pin 3mm x 3mm MLF(TM) package.
