MIC2288

1A, 1.2 MHz PWM Boost Converter in Thin SOT23 and DFN Packages

Features

General Description

• 2.5V to 10V Input Voltage Range

• Output Voltage Adjustable to 34V

• Over 1A Switch Current

The MIC2288 is a 1.2 MHz PWM, DC/DC boost

switching regulator available in low profile Thin SOT23

and 2 mm x 2 mm DFN package options. High-power

density is achieved with the MIC2288 device’s internal

34V/1A switch, allowing it to power large loads in a tiny

footprint.

• 1.2 MHz PWM Operation

• Stable with Ceramic Capacitors

• <1% Line and Load Regulation

• Low Output Voltage Ripple

The MIC2288 implements a constant frequency,

1.2 MHz PWM, Current-mode control scheme with

internal compensation that offers excellent transient

response and output regulation performance. The

high-frequency operation saves board space by allow-

ing small, low profile, external components. The fixed

frequency PWM topology also reduces spurious

switching noise and ripple to the input power source.

• <1 µA Shutdown Current

• Undervoltage Lockout

• Output Overvoltage Protection (MIC2288YML)

• Overtemperature Shutdown

• Thin 5-Lead SOT23 Package Option

• 2 mm x 2 mm Leadless 8-Lead DFN Package Option

• -40°C to +125°C Junction Temperature Range

The MIC2288 is available in a low profile 5-lead Thin

SOT23 package and a 2 mm x 2 mm 8-lead DFN lead-

less package. The DFN package option has an output

overvoltage protection feature.

Applications

• Organic EL Power Supply

The MIC2288 has a junction temperature range of

-40°C to +125°C.

• TFT-LCD Bias Supply

• 12V Supply for DSL Applications

• Multi-Output DC/DC Converters

• Positive and Negative Output Regulators

• SEPIC Converters
