MIC2205

2 MHz PWM Synchronous Buck Regulator with LDO Standby Mode

Feature

General Description

• 2.7 to 5.5V Supply Voltage

The MIC2205 is a high efficiency 2 MHz PWM

synchronous buck (step-down) regulator that features

an LDO standby mode that draws only 18 μA of

quiescent current. The MIC2205 allows an ultra-low

noise, small size, and high efficiency solution for

portable power applications.

• Light Load LDO Mode

- 18 μA Quiescent Current

- Low Noise, 75 μV_RMS

• 2 MHz PWM Mode

- Output Current to 600 mA

In PWM mode, the MIC2205 operates with a constant

frequency 2 MHz PWM control. Under light load

conditions, such as in system sleep or standby modes,

the PWM switching operation can be disabled to

reduce switching losses. In this light load mode, the

LDO maintains the output voltage and draws only

18 μA of quiescent current. The LDO mode of

operation saves battery life while not introducing

spurious noise and high ripple as experienced with

pulse skipping or bursting mode regulators.

- >95% Efficiency

- 100% Maximum Duty Cycle

• Adjustable Output Voltage Option Down to 1V

- Fixed Output Voltage Options Available

• Ultra-Fast Transient Response

• Stable with 1 μF Ceramic Output Capacitor

• Fully Integrated MOSFET Switches

• Micropower Shutdown

• Thermal Shutdown and Current Limit Protection

• Pb-Free 3 mm x 3 mm VDFN Package

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

The MIC2205 operates from 2.7V to 5.5V input and

features internal power MOSFETs that can supply up to

600 mA output current in PWM mode. It can operate

with a maximum duty cycle of 100% for use in low

dropout conditions.

Applications

• Cellular Phones

• PDAs

The MIC2205 is available in a 3 mm x 3 mm VDFN-10L

package with an operating junction temperature range

from –40°C to +125°C.

• USB Peripherals
