MIC23153

4 MHz PWM 2A Buck Regulator with

HyperLight Load^®and Power Good

Features

General Description

• Input Voltage: 2.7V to 5.5V

The MIC23153 is a high-efficiency 4 MHz 2A

synchronous buck regulator with HyperLight Load^®

mode, Power Good (PG) output indicator, and

programmable soft-start. HyperLight Load^®provides

very high efficiency at light loads and ultra-fast

transient response that makes the MIC23153 perfectly

suited for supplying processor core voltages.

• Output Voltage: Fixed or Adjustable (0.62V to

3.6V)

• Up to 2A Output Current

• Up to 93% Peak Efficiency

• 85% Typical Efficiency at 1 mA

• Power Good (PG) Output

An additional benefit of this proprietary architecture is

very low output ripple voltage throughout the entire

load range with the use of small output capacitors. The

tiny 2.5 mm x 2.5 mm thin DFN package saves

precious board space and requires only four external

components.

• Programmable Soft-Start

• 22 µA Typical Quiescent Current

• 4 MHz PWM Operation in Continuous Mode

• Ultra-Fast Transient Response

• Low Ripple Output Voltage:

- 35 mV_PPRipple in HyperLight Load^®Mode

The MIC23153 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 total solution size, less

than 1 mm in height.

- 5 mV Output Voltage Ripple in Full PWM

Mode

• Fully Integrated MOSFET Switches

The MIC23153 has a very-low quiescent current of

22 µA and achieves a peak efficiency of 93% in

continuous conduction mode. In discontinuous

conduction mode, the MIC23153 can achieve 85%

efficiency at 1 mA.

• 0.01 µA Shutdown Current

• Thermal Shutdown and Current Limit Protection

• 10-Pin 2.5 mm x 2.5 mm Thin DFN Package

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

The MIC23153 is available in 10-pin 2.5 mm x 2.5 mm

TDFN package with an operating junction temperature

range from –40°C to +125°C.

Applications

• Solid State Drives (SSD)

• Mobile Handsets

• Portable Media/MP3 Players

• Portable Navigation Devices (GPS)

• WiFi/WiMax/WiBro Modules

• Wireless LAN Cards

• Portable Applications
