MAX618

28V Internal Switch, Step-Up DC-DC Converter

General Description

Features

● Adjustable Output Voltage Up to +28V

The MAX618 CMOS, PWM, step-up DC-DC converter

generates output voltages up to 28V and accepts inputs

from +3V to +28V. An internal 2A, 0.3Ω switch eliminates

the need for external power MOSFETs while supplying

output currents up to 500mA or more. A PWM control

scheme combined with Idle Mode™ operation at light

loads minimizes noise and ripple while maximizing effi-

ciency over a wide load range. No-load operating current

is 500μA, which allows efficiency up to 93%.

● Up to 93% Efficiency

● Wide Input Voltage Range (+3V to +28V)

● Up to 500mA Output Current at +12V

● 500μA Quiescent Supply Current

● 3μA Shutdown Current

● 250kHz Switching Frequency

● Small 1W, 16-Pin QSOP Package

A fast 250kHz switching frequency allows the use of

small surface-mount inductors and capacitors. A shut-

down mode extends battery life when the device is not in

use. Adaptive slope compensation allows the MAX618 to

accommodate a wide range of input and output voltages

with a simple, single compensation capacitor.

16 QSOP

The MAX618 is available in a thermally enhanced 16-pin

QSOP package that is the same size as an industry-

standard 8-pin SO but dissipates up to 1W. An evaluation

kit (MAX618EVKIT) is available to help speed designs.
