MAX1653ESE+T

DC DC Switching Controllers Overview

The MAX1653ESE+T is a high-efficiency, pulse-width modulation (PWM) step-down DC-DC switching controller manufactured by Analog Devices Inc./Maxim Integrated. Designed for positive output applications, it operates within an input voltage range of 4.5V to 27V and supports output voltages from 0.8V to 20V. The device features a fixed 500kHz switching frequency and integrates a power MOSFET capable of delivering up to 3A load current. It utilizes an SOIC-16 narrow package and functions reliably across an operating temperature range of -40°C to +85°C.

DC DC Switching Controllers Feature Summary

• Integrates a high-current power MOSFET for compact solution design
• Fixed 500kHz switching frequency minimizes external component size
• Enables precise output voltage regulation via external resistor divider
• Includes thermal shutdown and cycle-by-cycle current limiting protection

DC DC Switching Controllers Applications

• Point-of-load regulation in industrial equipment
• Battery-powered systems requiring efficient step-down conversion
• Embedded control boards with single-supply requirements

DC DC Switching Controllers Procurement Notes

Verify the specific suffix '+T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations. Ensure the ordering part number matches the exact pinout and electrical specifications required for your circuit design before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this component for designs requiring a robust, integrated buck controller with moderate current capabilities. It is suitable where board space is limited due to the internal MOSFET and fixed frequency operation. Evaluate input voltage stability and thermal management needs against the specified operating range and package thermal characteristics.

DC DC Switching Controllers Part Context

This part belongs to the Maxim Integrated line of switching controllers, now under Analog Devices. It serves as a cost-effective solution for general-purpose DC-DC conversion tasks. The 'E' suffix typically denotes commercial/industrial temperature grades, while '+T' specifies the reel packaging format for automated assembly processes.

DC DC Switching Controllers Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure any replacement maintains compatible input/output voltage ranges, current handling capacity, and pin configuration to avoid redesign efforts.
