MIC23030

8 MHz PWM 400 mA Buck Regulator with HyperLight Load^®

Features

General Description

• Input Voltage: 2.7V to 5.5V

The MIC23030 is a high-efficiency, 8 MHz, 400 mA

synchronous buck regulator with HyperLight Load^®

mode. HyperLight Load^®provides very high efficiency

at light loads and ultra-fast transient response that is

perfectly suited for supplying processor core voltages.

An additional benefit of this proprietary architecture is

the very low output ripple voltage throughout the entire

load range with the use of small output capacitors. The

tiny 1.6 mm x 1.6 mm TDFN package saves precious

board space and requires only three external

components.

• 400 mA Output Current

• Up to 91% Efficiency and 83% at 1 mA

• 21 µA Typical Quiescent Current

• 8 MHz PWM Operation in Continuous Mode

• Ultra-Fast Transient Response

• Low Voltage Output Ripple

- 14 mV_PPRipple in HyperLight Load^®Mode

- 5 mV Output Voltage Ripple in Full PWM

Mode

The MIC23030 is designed for use with a very small

inductor, down to 0.47 µH, and an output capacitor as

small as 2.2 µF that enables a sub 1 mm height.

• Fully Integrated MOSFET Switches

• 0.01 µA Shutdown Current

• Thermal Shutdown and Current-Limit Protection

The MIC23030 has a very low quiescent current of

21 µA and achieves as high as 83% efficiency at 1 mA.

At higher loads, the MIC23030 provides a constant

switching frequency around 8 MHz while achieving

peak efficiencies up to 91%.

• Fixed and Adjustable Output Voltage Options

Available

• 1.6 mm x 1.6 mm 6-Lead TDFN Package

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

The MIC23030 is available in a 6-pin 1.6 mm x 1.6 mm

TDFN package with an operating junction temperature

range of –40°C to +125°C.

Applications

• Mobile Handsets

• Portable Media/MP3 Players

• Portable Navigation Devices (GPS)

• WiFi/WiMax/WiBro Modules

• Digital Cameras

• Wireless LAN Cards

• USB-Powered Devices

• Portable Applications
