MIC23650

6A Step-Down Converter

with HyperLight Load™ and Output Voltage Select

Features

General Description

• 2.4V to 5.5V Input Voltage Range

• 6A (Pulsed) Output Current

The MIC23650 is a high-efficiency, low-voltage, 6A

peak 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.

• Pin Strapping Voltage Selection:

- Three-State pins (nine voltage options)

- 0.6V, 0.8V, 0.9V, 1.0V, 1.2V, 1.5V, 1.8V, 2.5V

or 3.3V output voltage

The MIC23650 output voltage is set by two V_SEL

(Voltage Selection) pins, between nine different values.

This method eliminates the need for an external

feedback resistor divider and improves the output

voltage setting accuracy.

• Reduced Component Count (No Feedback

Resistors)

• High Efficiency (up to 95%)

• Output Discharge when Disabled

The 2.4V to 5.5V input voltage range, low shutdown

and quiescent currents make the MIC23650 ideal for

single-cell Li-Ion battery-powered applications. The

100% duty cycle capability provides low dropout

operation, extending operating range in portable

systems.

• Constant-ON-Time Control with High Switching

Frequency:

- 1.2 MHz typical at 1.0V output voltage

• ±1.5% Output Voltage Accuracy Over

Line/Load/Temperature Range

• 0.8 ms/V Soft Start Speed

The MIC23650 pinout is compatible with the MIC23656

I²C-based programmable regulator version, such that

applications can be easily converted. An open-drain

Power Good output is provided to indicate when the

output voltage is within 9% of regulation and facilitates

the interface with an MCU, or power sequencing. If set

in shutdown (EN=GND), the MIC23650 typically draws

1.5 µA, while the output is discharged through 10

pull-down.

• Supports Safe Start-Up with Pre-Biased Output

• Typical 1.5 µA Shutdown Supply Current

• Low Dropout Operation (100% Duty Cycle)

• Ultra Fast Transient Response

• Latch-Off Thermal Shutdown Protection

• Latch-Off Current Limit Protection

• Power Good (PG) Open-Drain Output

The MIC23650 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
