MIC23656

6A, Step-Down Converter

with HyperLight Load™ and I²C Interface

Features

General Description

• Input Voltage Range: 2.4V to 5.5V

• 6A (pulsed) Output Current

• Multiple Faults Indication through I²C

• I²C Programmable:

The MIC23656 is a high-efficiency, low-voltage input,

6A peak current synchronous step-down regulator. The

Constant-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 - 10A

- 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 MIC23656 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 MIC23656 pinout is compatible with the

MIC23650, 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 MIC23656 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 MIC23656 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
