Overview
The TC62D776CFG,EL is a 16-channel constant-current LED driver IC designed for 3.3-V and 5-V power supply systems. It features an internal shift register topology with linear current regulation, delivering up to 90mA per channel. The device supports a supply voltage range of 3V to 5.5V and output voltages up to 17V. Packaged in a 24-SSOP surface-mount format, it operates within a temperature range of -40°C to 85°C.
Feature Summary
- Integrates a 16-channel constant-current driver with internal shift register control for simplified serial interface operation.
- Provides linear current regulation across all channels to ensure uniform LED brightness without external current-setting components.
Applications
- LED lighting systems
- Display backlighting applications
Procurement Notes
Verify component authenticity through authorized Toshiba Semiconductor and Storage distributors or certified partners. Confirm the specific suffix 'CFG,EL' matches the required tape-and-reel packaging configuration. Check RoHS compliance status against current environmental regulations. Validate that the obsolete or EOL status does not impact long-term project viability before finalizing procurement decisions.
Selection Notes
Select this component when a 16-channel solution is required for 3.3V or 5V logic-controlled LED arrays. Ensure the design accommodates the 24-SSOP package dimensions and thermal requirements. Verify that the 90mA per-channel output capability aligns with the target LED forward current specifications. Consider the linear topology's efficiency implications compared to switching alternatives for the specific application power budget.
Part Context
This part belongs to Toshiba's dedicated LED driver family, utilizing shift register architecture for multi-channel control. It serves as a specialized power management IC for managing multiple LEDs from a single serial interface, distinct from general-purpose PMICs or simple single-channel drivers.
Replacement Considerations
Public documentation identifies the TC62D749CFG,EL as a related variant within the same product line. Both devices share identical electrical characteristics, including 16 channels, 90mA output, and 24-SSOP packaging. Verify pin-to-pin compatibility and functional equivalence before substituting.
