Buck regulator

Monday, 01 June, 2009 | Supplied by: Future Electronics


Micrel has introduced the latest member of its high power density family of products, the MIC22700.

The device is a 7 A integrated synchronous buck (step-down) regulator. It achieves more than 95% efficiency, while still switching at 1 MHz over a broad load range with only 1 µH inductor and a 47 µF output capacitor.

It also features built-in sequencing, tracking and ramp control — enabling all power-up sequencing and tracking protocols. It is suitable for high power density point-of-load conversion, servers and routers, DVD recorders, computing peripherals, base stations, FPGAs, DSP and low-voltage ASIC power applications.

The device 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 0.7 to address all low-voltage power needs, from a 3.3 or 5 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 ramp control pin allows the device to be connected to another product in the MIC22xxx and/or the MIC68xxx family.
