28V, PWM, Step-Up DC-DC Converter  
MAX618  
General Description  
Features  
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, 0.3switch  
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%.  
o Adjustable Output Voltage Up to +28V  
o Up to 93% Efficiency  
o Wide Input Voltage Range (+3V to +28V)  
o Up to 500mA Output Current at +12V  
o 500µA Quiescent Supply Current  
o 3µA Shutdown Current  
o 250kHz Switching Frequency  
o 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.  
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.
