MAX764CSA

MAX764CSA Description

The MAX764CSA from Analog Devices Inc./Maxim Integrated is a high-efficiency, adjustable/fixed negative-output DC-DC switching regulator designed for compact, low-power applications. Operating within an input voltage range of 3V to 16V, it delivers a 260mA output current with a switching frequency of 300kHz, ensuring stable performance in space-constrained designs. Housed in an 8-pin SOIC package, this regulator is optimized for surface-mount assembly and is ideal for portable and battery-powered systems. Although marked as obsolete, it remains relevant for legacy designs requiring reliable, low-noise power conversion.

MAX764CSA Features

• Adjustable/Fixed Output: Configurable for adjustable negative voltage or fixed -1V output, offering design flexibility.
• Wide Input Range (3V–16V): Supports diverse power sources, including batteries and unregulated supplies.
• High Efficiency (300kHz Switching): Minimizes power loss and heat dissipation, enhancing thermal performance.
• Compact & Robust: 8-SOIC package with MSL 1 (Unlimited) moisture sensitivity, suitable for industrial environments.
• Non-Synchronous Rectification: Simplifies design while maintaining efficiency for low-to-moderate current applications.

MAX764CSA Applications

• Portable Electronics: Ideal for battery-powered devices like handheld instruments, where efficiency and size are critical.
• Negative Bias Supplies: Used in op-amp circuits, data converters, and sensors requiring stable negative voltages.
• Legacy Systems Maintenance: Suitable for servicing older equipment where replacement with modern equivalents is impractical.
• Industrial Controls: Reliable performance in 0°C to 70°C environments makes it fit for industrial automation modules.

Conclusion of MAX764CSA

The MAX764CSA stands out for its versatile output options, compact form factor, and robust performance in demanding conditions. While obsolete, its wide input range and efficient power conversion make it a pragmatic choice for niche applications. Engineers valuing reliability and simplicity in negative-voltage regulation will find it particularly useful, especially in legacy or space-constrained designs. For new projects, however, exploring newer alternatives with advanced features (e.g., synchronous rectification) is recommended.
