General Desc ription
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, 0.3
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 oper-
ation at light loads minimizes noise and ripple while
maximizing efficiency over a wide load range. No-load
operating current is 500μA, which allows efficiency up
to 93%.
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.
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.
