Regulator Redefines "High Power Density" from Micrel
Micrel , represented in Australia and New Zealand by Soanar, has released the the MIC22950 synchronous step-down regulator. The device features 10A integrated SuperThermalTM MOSFETs and is optimized for highest efficiency. Requiring a 1µH inductor and a 100µF output capacitor, the device achieves more than 95 percent efficiency over a broad load range. It also features built-in sequencing, tracking and ramp control capabilities — enabling multiple power-up sequencing and tracking protocols. The solution is ideal for high power density point-of-load conversion, base stations, servers and routers, Blu-ray players, computer peripherals, FPGAs, DSPs and low voltage ASIC power applications.
The MIC22950 has an ultra-high speed control loop that keeps the output voltage within regulation even under extreme transient load swings that are commonly found in FPGAs and low voltage ASICs. The output voltage can be adjusted down to 0.7V to address all low voltage power needs, from a 3.3V or 5V power bus. A full range of sequencing and tracking options is available. The Enable/Delay pin, combined with the Power Good/POR pin, allows multiple outputs to be sequenced as desired during turn-on and turn-off. The RC (Ramp Control™) pin allows the device to be connected to another product in Micrel's MIC22xxx and/or its MIC68xxx family, thereby allowing the designer to maintain the output voltages within a certain delta-V on start up. The MIC22950 has thermal shutdown and current limit protection, is available in a 32-pin 5mm x 5mm MLF®, and offers a junction operating range from -40°C to +125°C.
