Procurement Notes
Verify the discontinuation status of the AHK1421ICA-T1 before initiating any procurement activities. As the component is marked as discontinued, availability may be limited to surplus stock or obsolete inventory channels. Confirm package integrity and authenticity through authorized distributors or verified secondary market sources. Ensure that alternative components are evaluated for pin compatibility and electrical performance if replacement is required for ongoing production.
Selection Notes
Select this component only for legacy designs requiring a specific serial LED boost driver in a TSOT23-6 package. Evaluate the 31mA output current capability against the target LED string requirements. Consider the 1MHz switching frequency for electromagnetic interference (EMI) management in compact layouts. Verify that the S²Cwire interface aligns with the system controller's communication capabilities. Assess the impact of the discontinued status on long-term supply chain stability.
Part Context
The AHK1421 belongs to the PMIC - LED Drivers family from Skyworks Solutions. It is designed specifically for low-power portable electronics where space and efficiency are critical. The integration of the boost converter and driver reduces the external component count compared to discrete solutions. This part represents an earlier generation of Skyworks' LED driving technology, preceding more recent multi-channel or higher-current offerings.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, engineers must identify equivalent components based on package type (TSOT23-6), output current (approx. 30mA), and interface compatibility (serial/S²Cwire). Cross-reference with current Skyworks LED driver portfolios or third-party equivalents for functional parity.
