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
