MIC22200

4 MHz 2A Synchronous Buck Regulator with Programmable Frequency

Features

General Description

• Input Voltage Range: 2.6V to 5.5V

• Output Voltage Adjustable Down to 0.7V

• Output Load Current Up to 2A

The MIC22200 is a high-efficiency, 2A integrated

switch synchronous buck (step-down) regulator. The

MIC22200 switching frequency is programmable from

800 kHz to 4 MHz, 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 1 MHz over a broad load

range.

• Full Sequencing and Tracking Ability

• Easy RC Compensation

• Power-on-Reset (POR) Output

• Efficiency >90% Across a Broad Load Range

• Operating frequency: Programmable from

800 kHz up to 4 MHz

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.

• Ultra-Fast Transient Response

• 100% Maximum Duty Cycle

The output voltage can be adjusted down to 0.7V to

address all low voltage power needs.

• 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 ∆V

on start up.

• Thermal Shutdown and Current-Limit Protection

• Available in 12-Pin 3 mm x 3 mm DFN

• –40°C to +125°C Junction Temperature Range

Applications

• High Power Density Point-of-Load Conversion

• Servers and Routers

The MIC22200 is available in a 12-pin 3 mm x 3 mm

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

+125°C.

• DVD Recorders and Multimedia Players

• Computing Peripherals

• Base Stations

• FPGAs, DSP, and Low Voltage ASIC Devices
