2A Integrated Switch Synchronous

Buck Regulator with Frequency

Programmable from 800kHz to 4MHz

General Description

Features

The Micrel MIC22200 is a high-efficiency, 2A integrated

switch synchronous buck (step-down) regulator. The

MIC22200 switching frequency is programmable from

800kHz to 4MHz, allowing the customer to optimize their

designs either for efficiency or for the smallest footprint.

The regulator achieves efficiencies as high as 95% while

still switching at 1MHz over a broad load range.

• Input voltage range: 2.6V to 5.5V

• Adjustable output voltage option down to 0.7V

• Output load current to 2A

• Full sequencing and tracking capability

• Easy RC compensation

• Power-On-Reset (POR) output

The ultra high-speed control loops keep the output voltage

within regulation even under the extreme transient load

swings commonly found in FPGAs and low-voltage ASICs.

• Efficiency >90% across a broad load range

• Operating frequency: Programmable from 800 kHz up to

4MHz

The output voltage can be adjusted down to 0.7V to

address all low-voltage power needs.

• Ultra-fast transient response

• 100% maximum duty cycle

• Fully integrated MOSFET switches

• Micropower shutdown

The MIC22200 offers a full range of sequencing and

tracking options. The EN/DLY pin, combined with the

Power-On-Reset (POR) pin, allows multiple outputs to be

sequenced in many ways during turn on and turn off. The

RC (ramp control) pin allows the device to be connected to

another device in the MIC22X00 family of products to keep

the output voltages within a certain delta V on start up.

The MIC22200 is available in a 3mm × 3mm 12-pin MLF^®

package with a junction operating range from –40°C to

+125°C.

• Thermal-shutdown and current-limit protection

• Available in Pb-free 3mm × 3mm MLF-12-pin MLF^®

Package

• –40°C to +125°C junction temperature range

Applications

• High power density point-of-load conversion

• Servers/routers

• DVD recorders and multimedia players

• Computing peripherals

Data sheets and support documentation can be found on

Micrel’s web site at www.micrel.com.

• Base stations

• FPGAs, DSP and low voltage ASIC devices
