MIC2296

High Power Density 1.2A

Boost Regulator

General Description

Features

The MIC2296 is a 600kHz, PWM dc/dc boost switching

regulator available in a 2mm x 2mm MLF^®package option.

High power density is achieved with the MIC2296’s

internal 34V / 1.2A switch, allowing it to power large loads

in a tiny footprint. The MIC2296 is a version of the

MIC2295 1.2MHz, PWM dc/dc boost switching regulator,

that offers improved efficiency resulting from 600kHz

operation.

• 2.5V to 10V input voltage range

• Output voltage adjustable to 34V

• 1.2A switch current

• 600kHz PWM operation

• Stable with small size ceramic capacitors

• High efficiency

• Low input and output ripple

• <1µA shutdown current

• UVLO

• Output over-voltage protection (MIC2296BML)

• Over temperature shutdown

• 2mm x 2mm leadless 8-pin MLF^®package option

• –40^oC to +125^oC junction temperature range

The MIC2296 implements constant frequency 600kHz

PWM current mode control. The MIC2296 offers internal

compensation that offers 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.

The MIC2296 is available in a low-profile Thin SOT23 5-

pin package and a 2mm x2mm 8-pin MLF^®leadless

package. The 2mm x 2mm MLF^®package option has an

output over-voltage protection feature.

Applications

• Organic EL power supplies

• 3.3V to 5V/500mA conversion

• TFT-LCD bias supplies

• Positive and negative output regulators

• SEPIC converters

The MIC2296 has an operating junction temperature range

of –40°C to +125°C

• Positive to negative Cuk converters

• 12V supply for DSL applications

• Multi-output dc/dc converters
