MIC23153

4MHz PWM 2A Buck Regulator with

HyperLight Load™ and Power Good

General Description

Features

• Input voltage: 2.7V to 5.5V

The MIC23153 is

high-efficiency, 4MHz, 2A,

• Output voltage: fixed or adjustable (0.62V to 3.6V)

• Up to 2A output current

• Up to 93% peak efficiency

• 85% typical efficiency at 1mA

• Power Good output

• Programmable soft-start

synchronous buck regulator with HyperLight Load™ mode,

Power Good output indicator, and programmable soft-start.

HyperLight Load™ provides very-high efficiency at light

loads and ultra-fast transient response which makes the

MIC23153 perfectly suited for supplying processor core

voltages. 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 2.5mm x 2.5mm Thin MLF^®package

saves precious board space and requires only four

external components.

• 22µA typical quiescent current

• 4MHz PWM operation in continuous mode

• Ultra-fast transient response

• Low ripple output voltage

− 35mVpp ripple in HyperLight Load^™mode

− 5mV output voltage ripple in full PWM mode

• Fully integrated MOSFET switches

The MIC23153 is designed for use with a very-small

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

as 2.2 µF that enables a total solution size, less than 1mm

in height.

• 0.01µA shutdown current

• Thermal shutdown and current-limit protection

• 10-pin 2.5mm x 2.5mm Thin MLF^®

The MIC23153 has a very-low quiescent current of 22µA

and achieves a peak efficiency of 93% in continuous

conduction mode. In discontinuous conduction mode, the

MIC23153 can achieve 85% efficiency at 1mA.

• –40°C to +125°C junction temperature range

Applications

• Solid State Drives (SSD)

• Mobile handsets

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

MLF^®package with an operating junction temperature

range from –40°C to +125°C.

• Portable navigation devices (GPS)

• WiFi/WiMax/WiBro modules

• Wireless LAN cards

• Portable applications
