MIC2605/6  
0.5A, 1.2 MHz/2 MHz Wide Input Range Boost Regulators,  
Each with Integrated Switch and Schottky Diode  
Features  
General Description  
• Wide Input Voltage Range: 4.5V to 20V  
• Output Voltage Adjustable to 40V  
• 0.5A Switch Current and Schottky Diode  
• MIC2605 Operates at 1.2 MHz  
• MIC2606 Operates at 2 MHz  
• Programmable Soft-Start  
The MIC2605 and MIC2606 are PWM DC/DC boost  
switching regulators each available in a 8-lead 2 mm x  
2 mm TDFN package. The only difference between the  
2 versions of the device is the switching frequency: The  
MIC2605 runs at 1.2 MHz, while the MIC2606 runs at  
2 MHz. High power density is achieved with the internal  
40V switch and 0.5A Schottky diode in both the  
MIC2605 and MIC2606, allowing them to power large  
loads in a tiny footprint.  
• Stable with Small Size Ceramic Capacitors  
• High Efficiency  
The MIC2605 and MIC2606 implement constant  
frequency 1.2 MHz and 2 MHz (respectively) PWM  
current mode control. The MIC2605 and MIC2606 offer  
internal compensation with excellent transient  
response and output regulation performance. The high  
frequency operation saves board space by allowing  
small, low-profile external components. The fixed  
frequency PWM scheme also reduces spurious  
switching noise and ripple to the input power source.  
• Low Input and Output Ripple  
• <10 μA shutdown current  
• UVLO  
• Output Overvoltage and Overtemperature  
Protection  
• 8-lead 2 mm x 2 mm TDFN Package  
• –40°C to +125°C Junction Temperature Range  
Applications  
• TV Tuners  
The MIC2605 and MIC2606 are each available in an  
8-lead 2 mm × 2 mm TDFN leadless package. This  
package has an output overvoltage protection feature.  
• Broadband Communications  
• TFT-LCD Bias Supplies  
• Bias Supply  
The MIC2605 and MIC2606 both have operating  
junction temperature ranges of –40°C to +125°C.  
• Positive Output Regulators  
• SEPIC Converters  
• DSL Applications  
Package Types  
• Local Boost Regulators
