MIC23156

1.5A, 3 MHz Synchronous Buck Regulator with HyperLight Load^®

and I²C Control for Dynamic Voltage Scaling

Features

General Description

• Input Voltage: 2.7V to 5.5V

• Up to 1.5A Output Current

• 1 MHz I²C Controlled Adjustable Output:

The MIC23156 is a high-efficiency, 1.5A synchronous

buck regulator with HyperLight Load^®mode and

dynamic voltage scaling control through I²C. HyperLight

Load provides very high efficiency at light loads and

ultra-fast transient response. The ability to dynamically

change the output voltage and maintain high output volt-

age accuracy make the MIC23156 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. Fast mode plus I²C provides

output voltage and chip enable/disable control from a

standard I²C bus with I²C clock rates of 100 kHz,

400 kHz, and 1 MHz.

V_OUT= 0.7 to 2.4V in 10 mV Steps

• High Output Voltage Accuracy

(±1.5% over Temperature)

• Fast Pin-Selectable Output Voltage

• Programmable Soft-Start Using External Capaci-

tor

• Ultra-Low Quiescent Current of 30 µA when

Not Switching

• Thermal Shutdown and Current-Limit Protection

• Safe Start-Up into Pre-Biased Output

• Stable with 1 µH Output Inductor and

2.2 µF Ceramic Capacitor

The MIC23156 is designed for use with 1 µH, and an

output capacitor as small as 2.2 µF, that enables a total

solution size less than 1 mm in height.

• Up to 93% Peak Efficiency

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

Package Types

• Available in 16-ball, 0.4 mm pitch, 1.81 mm x

1.71 mm Wafer Level Chip-Scale (WLCSP) and

17-pin, 2.8 mm x 2.5 mm QFN Packages
