Dual-Output (+ and -) DC-DC  
Converters for CCD  
General Description  
Features  
The MAX8614A/MAX8614B dual-output step-up DC-DC  
converters generate both a positive and negative sup-  
ply voltage that are each independently regulated. The  
positive output delivers up to 50mA while the inverter  
supplies up to 100mA with input voltages between 2.7V  
and 5.5V. The MAX8614A/MAX8614B are ideal for pow-  
ering CCD imaging devices and displays in digital  
cameras and other portable equipment.  
Dual Output Voltages (+ and -)  
Adjustable Up to +24V and Down to -10V at 5.5V  
Output Short/Overload Protection  
True Shutdown on Both Outputs  
Controlled Inrush Current During Soft-Start  
Selectable Power-On Sequencing  
Up to 90% Efficiency  
IN  
The MAX8614A/MAX8614B generate an adjustable  
positive output voltage up to +24V and a negative out-  
put down to 16V below the input voltage. The  
MAX8614B has a higher current limit than the  
MAX8614A. Both devices operate at a fixed 1MHz fre-  
quency to ease noise filtering in sensitive applications  
and to reduce external component size.  
1µA Shutdown Current  
1MHz Fixed-Frequency PWM Operation

Thermal Shutdown  
Small, 3mm x 3mm, 14-Pin TDFN Package  
Additional features include pin-selectable power-on  
sequencing for use with a wide variety of CCDs, True  
Shutdown™, overload protection, fault flag, and internal  
soft-start with controlled inrush current.
