ILC6383CIRADJX

Voltage Regulators - DC DC Switching Regulators Overview

The ILC6383CIRADJX is a step-up DC-DC converter manufactured by Fairchild Semiconductor, operating from a 1V to 6V input range. It provides an adjustable output voltage up to 6V with a maximum switch current of 1A. The device features synchronous rectification and operates at a fixed internal oscillator frequency of 300kHz. Designed for low-power portable applications, it supports both PFM and PWM modes selectable via the SEL pin. The component is housed in an 8-MSOP package and functions as a direct replacement for the ILC6382 when the SYNC pin is unused.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Synchronous rectification architecture eliminates the need for external diodes
• True load disconnect capability isolates the battery input during shutdown
• User-selectable PFM or PWM operation modes optimize efficiency based on load conditions
• Integrated low battery detector includes transient rejection delay

Voltage Regulators - DC DC Switching Regulators Applications

• Cellular phones and pagers
• Palmtops and PDAs
• Portable electronics devices
• High efficiency 1V step-up converters

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'CIRADJX' to confirm the adjustable output variant and MSOP packaging. Ensure compatibility with existing PCB footprints for the 8-MSOP form factor. Confirm that the application design does not require the SYNC pin functionality, as this part replaces the ILC6382 only when that pin is inactive. Check for lead-free compliance status if required by assembly specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an adjustable boost voltage up to 6V is required from a single-cell lithium-ion or similar power source. Choose the ILC6383CIRADJX over fixed-output variants when system flexibility for varying rail voltages is necessary. Consider the 1A switch current limit for load requirements and ensure the 300kHz switching frequency aligns with electromagnetic interference constraints in the target design.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the ILC6383 series of 1-cell to 3-cell boost DC-DC converters. It serves as a successor to the ILC6382, offering enhanced integration through synchronous rectification. The series is engineered for wireless communications and portable consumer electronics, prioritizing high peak efficiency exceeding 90% and minimal quiescent current consumption in standby modes.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The ILC6383CIRADJX is documented as a direct replacement for the ILC6382 in applications where the SYNC pin is not utilized. Verify that the original design does not depend on synchronization capabilities provided by the legacy component.
