MAX630CSA Description

The MAX630CSA from Analog Devices Inc./Maxim Integrated is an adjustable boost DC-DC switching voltage regulator designed for applications requiring efficient step-up voltage conversion. With an input voltage range of 2.2V to 16.5V and an adjustable output voltage up to 18V (switch), it delivers a switching current of 525mA, making it suitable for low-to-medium power applications. The device operates at a fixed switching frequency of 40kHz, ensuring stable performance with minimal external components. Packaged in an 8-pin SOIC and rated for 0°C to 70°C (TA), it is ideal for surface-mount designs in industrial and consumer electronics.

MAX630CSA Features

• Wide Input Range (2.2V–16.5V): Supports battery-powered and low-voltage systems.
• Adjustable Output (2.2V–18V): Flexibility for diverse voltage requirements.
• High Switching Current (525mA): Efficient power delivery for compact designs.
• 40kHz Fixed Frequency: Simplifies filtering and reduces noise.
• Single Positive Output: Streamlined for unipolar applications.
• Surface-Mount (SOIC-8): Space-saving and suitable for automated assembly.
• Non-Synchronous Rectification: Cost-effective for basic boost topologies.

MAX630CSA Applications

The MAX630CSA excels in scenarios requiring compact, efficient voltage boosting, such as:

• Battery-Powered Devices: Extends operating voltage in portable electronics (e.g., sensors, handheld instruments).
