Low-Noise Step-Up DC-DC Converter

MAX1067

General Description

Features

The MAX17067 boost converter incorporates high-

performance (at 1.2MHz), current-mode, fixed-frequency,

pulse-width modulation (PWM) circuitry with a built-in

0.15Ω n-channel MOSFET to provide a highly efficient

regulator with fast response.

o 90% Efficiency

o Adjustable Output from V to 18V

o 2.4A, 0.15Ω, 22V Power MOSFET

o +2.6V to +4.0V Input Range

High switching frequency (640kHz or 1.2MHz selectable)

allows for easy filtering and faster loop performance. An

external compensation pin provides the user flexibility in

determining loop dynamics, allowing the use of small,

low equivalent-series-resistance (ESR) ceramic output

capacitors. The device can produce an output voltage

as high as 18V.

o Pin-Selectable 640kHz or 1.2MHz Switching

Frequency

o Programmable Soft-Start

o Small 8-Pin µMAX Package

o Integrated Input Voltage Clamp Circuit

Soft-start is programmed with an external capacitor, which

sets the input-current ramp rate. The MAX17067 is avail-

able in a space-saving 8-pin μMAX^®package. The ultra-

small package and high switching frequency allow the

total solution to be less than 1.1mm high.
