Maxim Integrated MAX8597
The MAX8597 is available in a 20-pin thin QFN package and is designed for applications that use an analog signal to control the output voltage with an adjustable offset, such as DC fan-speed control. This is achieved with an internal uncommitted operational amplifier. The MAX8597 is also targeted for tracking output-voltage applications for chipsets, ASIC and DSP cores, and I/O supplies.| Part No. | MAX8597 |
