MIC23356  
3A, Step-Down Converter  
with HyperLight Loadand I2C Interface  
Features  
General Description  
• Input Voltage Range: 2.4V to 5.5V  
• 3A Continuous Output Current  
• Multiple Faults Indication through I2C  
• I2C Programmable:  
The MIC23356 is a high-efficiency, low-voltage input,  
3A synchronous step-down regulator. The Con-  
stant-ON-Time (COT) control architecture with  
HyperLight Load™ provides very high efficiency at light  
loads, while still having ultra-fast transient response.  
The I2C interface allows programming the output volt-  
age between 0.6V and 1.28V, with 5 mV resolution or  
between 0.6V and 3.84V, with 10 mV and 20 mV reso-  
lution. Three different default voltage options (0.6V,  
0.9V and 1.0V) are provided so that the application can  
be started with a safe voltage level and then moved to  
high performance modes under I2C control.  
- Output Voltage: 0.6V - 1.28V, 5 mV  
Resolution or 0.6V - 3.84V, 10/20 mV  
Resolution  
- Slew Rate: 0.2 ms/V - 3.2 ms/V  
- ON Time (Switching Frequency)  
- High-Side Current Limit: 3.5A - 5A  
- Enable Delay: 0.2 ms - 3 ms  
- Output Discharge when Disabled  
(EN = GND)  
An open-drain Power Good output facilitates output  
voltage monitoring and sequencing. If set in shutdown  
(EN = GND), the MIC23356 typically draws 1.5 µA,  
while the output is discharged through 10pull-down  
(if the output discharge feature is enabled).  
• High Efficiency (up to 95%)  
• Ultra-Fast Transient Response  
• ±1.5% Output Voltage Accuracy Over  
Line/Load/Temperature Range  
The MIC23356 pinout is compatible with the  
MIC23350, so that applications can be easily  
converted.  
• Safe Start-Up with Pre-Biased Output  
• Typical 1.5 µA Shutdown Supply Current  
• Low Dropout (100% Duty Cycle) Operation  
• I2C Speed up to 3.4 MHz  
The 2.4V to 5.5V input voltage range, low shutdown  
and quiescent currents make the MIC23356 ideal for  
single-cell Li-Ion battery-powered applications. The  
100% duty cycle capability provides low dropout  
operation, extending operating range in portable  
systems.  
• Latch-Off Thermal Shutdown Protection  
• Latch-Off Current Limit Protection  
• Power Good (PG) Open-Drain Output  
The MIC23356 is available in a thermally efficient,  
16-Lead 2.5 mm x 2.5 mm x 0.55 mm thin FTQFN  
package, with an operating junction temperature range  
from -40°C to +125°C.  
Applications  
• Solid State Drives (SSD)  
• FPGAs, DSP and Low-Voltage ASIC Power
