MAX8614A/MAX8614B

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

supply 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

powering 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

● 1µA Shutdown Current

● 1MHz Fixed-Frequency PWM Operation

● Fault-Condition Flag

The MAX8614A/MAX8614B generate an adjustable

positive output voltage up to +24V and a negative

output down to 16V below the input voltage.

The MAX8614B has a higher current limit than the

MAX8614A. Both devices operate at a fixed 1MHz

frequency to ease noise filtering in sensitive applications

and to reduce external component size.

● Thermal Shutdown

● Small, 3mm x 3mm, 14-Pin TDFN Package

Ordering Information

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.
