MIC236566A Buck Regulator with HyperLight Load® & I2C | Voltage Regulators - DC DC Switching Regulators | 3 | Active | 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
mV 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 10W 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 x 2.5 mm x 0.55 mm thin FTQFN package, with an operating
junction temperature range from -40°C to +125°C |
