MAX1651CSA

DC DC Switching Controllers Overview

The MAX1651CSA+T is a high-efficiency, low-dropout voltage controller manufactured by Analog Devices Inc./Maxim Integrated. It operates with an input voltage range of 3 V to 16 V and provides a fixed 5 V output or an adjustable output ranging from 1.5 V to 16 V. The device supports an output current of 2.5 A and features a single output configuration. It is housed in an SO-8 surface-mount package and functions as a step-down converter within the PMIC category. The component is rated for operation between 0 C and +70 C.

DC DC Switching Controllers Feature Summary

• High-efficiency step-down voltage regulation
• Adjustable or fixed output voltage capability
• Low-dropout operation design

DC DC Switching Controllers Applications

• General-purpose power management in portable systems
• Battery-powered equipment requiring efficient voltage conversion
• Embedded systems needing stable 5V or adjustable rail generation

DC DC Switching Controllers Procurement Notes

Verify the exact suffix (e.g., +T) against the datasheet to confirm packaging type, as standard suffixes may indicate reel quantities while others denote tube packaging. Confirm RoHS compliance status directly with the manufacturer documentation, as availability and specific environmental certifications can vary by production batch and region. Ensure the ordering part number matches the required thermal and electrical specifications precisely.

DC DC Switching Controllers Selection Notes

Select this component when a single-output, high-current step-down solution is required within a narrow SO-8 footprint. It is suitable for designs where input voltages exceed the desired regulated output level significantly. Consider the thermal performance in the SO-8 package relative to the 2.5 A load requirement. Verify that the application does not require multiple independent outputs or higher switching frequencies than inherent to LDO controllers.

DC DC Switching Controllers Part Context

This part belongs to the MAX1651 series of low-dropout voltage controllers from Maxim Integrated, now part of Analog Devices. These devices are designed for applications demanding high efficiency and compact form factors. The CSA variant specifically denotes the SO-8 surface-mount package option, distinguishing it from other package styles available within the same functional family.
