LTC3610IWP

Voltage Regulators - DC DC Switching Regulators Overview

The LTC3610IWP is a monolithic synchronous step-down DC/DC converter manufactured by Analog Devices Inc. It delivers up to 12A of output current from an input voltage range of 4V to 24V, with a maximum rating of 28V. The device utilizes a valley current control architecture for high efficiency and excellent transient response. Operating frequency is selected via an external resistor and compensated for VIN and VOUT variations. It features very low duty cycle operation at high frequencies. The component is housed in a 64-lead HVQCCN package and operates within a temperature range of -40°C to 125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'IWP' against the manufacturer's official datasheet to confirm the industrial temperature grade (-40°C to 125°C) and the 64-lead HVQCCN package configuration. Ensure compatibility with lead-free or tin-lead soldering processes as specified in the ordering guide. Cross-reference the ECCN code EAR99 for export compliance requirements relevant to your region.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing systems requiring a single-stage solution for high-current applications with inputs up to 24V. The integrated synchronous switches eliminate the need for external Schottky diodes, reducing board space. Consider the external resistor for frequency setting to optimize efficiency versus EMI trade-offs. Verify that the thermal performance of the 64-lead QFN package meets the thermal resistance requirements of the final enclosure design.

Voltage Regulators - DC DC Switching Regulators Part Context

The LTC3610 belongs to Linear Technology's (now ADI) family of high-current synchronous step-down converters. It is designed to replace multi-phase discrete solutions or older controller-based designs in compact form factors. The IWP variant specifically denotes the industrial temperature range and the specific 64-lead plastic quad flat no-lead package suitable for automated surface-mount assembly.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Consult official ADI documentation for direct pin-compatible replacements within the LTC36xx series. Verify that any substitute maintains the 12A current capability and 24V input rating. Ensure the alternative device supports the same valley current control mode if low duty cycle performance is critical.
