Introduction

AI Translation

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 voltage between 0.6V and 1.28V, with 5 mV resolution or between 0.6V and 3.84V, with 10 and 20 mV resolution. 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. 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 Ω pull-down (if the output discharge feature is enabled). The MIC23656 pinout is compatible with the MIC23650, so that applications can be easily converted. 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. The MIC23656 is available in a thermally efficient, 16-Lead 2.5 mm × 2.5 mm × 0.55 mm thin FTQFN package, with an operating junction temperature range from -40°C to +125°C.
