MIC2204

High-Efficiency 2 MHz Synchronous Buck Converter

Feature

General Description

• Input Voltage range: 2.3V to 5.5V

• Output Down to 1V/ 600 mA

• 2 MHz PWM Operation

The MIC2204 is a high-efficiency, 2 MHz PWM

synchronous buck switching regulator. Power

conversion efficiency of above 95% is easily obtainable

over a wide range of applications. A proprietary internal

compensation technique ensures stability with the

smallest possible inductor and ceramic output

capacitor.

• Ultra-Fast Transient Response (Typical 200 kHz

GBW)

• Internal Compensation

• All Ceramic Capacitors

The MIC2204 operates from 2.3V to 5.5V input and

features internal power MOSFETs that can supply over

600 mA of output current with output voltages down to

1V. The MIC2204 implements a constant 2 MHz pulse

width modulation (PWM) control scheme which

reduces spurious noise in sensitive RF and

communication applications. Additionally, the MIC2204

can be synchronized to an external clock, or multiple

MIC2204 can easily be daisy chained with the

SYNCLOCK feature.

• >95% Efficiency

• Fully Integrated MOSFET Switches

• Easily Synchronized to External Clock

• SYNCLOCK Feature to Daisy Chain Multiple

2204

• <340 µA Quiescent Current

• Logic Controlled Micropower Shutdown

• Thermal Shutdown and Current Limit Protection

• 10-pin MSOP and 3 mm x 3 mm VDFN-10L

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

The MIC2204 has a high bandwidth loop (typ. 200 kHz)

which allows ultra-fast transient response times. This is

very useful when powering applications that require

fast dynamic responses, such as the CPU cores and

RF circuitry in high performance cellular phones and

PDAs.

Applications

• High-Efficiency Portable Power

• Cellular Phones/PDAs

• 802.11 WLAN Power Supplies

• RF Power Supplies

The MIC2204 is available in 10-pin MSOP and 3 mm x

3 mm VDFN-10L package options with an operating

junction temperature range from –40°C to +125°C.

• Li-Ion Battery Powered Applications
