Overview
The RT8470GJ5 is an LED driver IC manufactured by Richtek USA Inc., housed in a TSOT-23-5 package. It operates as a buck (step-down) converter with an input voltage range of 7V to 30V and a maximum output voltage of 26V. The device supports analogue or PWM dimming control methods. Key electrical specifications include a 30V rating and compatibility with surface-mount installation techniques, designed for efficient power management in lighting applications.
Feature Summary
- Integrates a synchronous buck converter topology for high-efficiency step-down operation
- Supports both analogue and pulse-width modulation (PWM) dimming control interfaces
- Designed for driving LEDs with adjustable output capabilities within specified voltage limits
Applications
- LED lighting systems requiring step-down conversion
- Portable devices utilizing PWM dimmable LED indicators
- General-purpose low-power LED driver circuits
Procurement Notes
Verify the specific suffix GJ5 against official Richtek documentation to confirm package type and temperature grade. Ensure compatibility with system input voltages between 7V and 30V. Check for moisture sensitivity levels and storage requirements prior to assembly. Confirm that the TSOT-23-5 footprint matches the design layout. Validate RoHS compliance status through current manufacturer declarations.
Selection Notes
Select this component when a compact, high-voltage input LED driver is required. The TSOT-23-5 package suits space-constrained designs. Consider the 7V minimum input requirement and 30V maximum rating for circuit compatibility. Evaluate whether analogue or PWM dimming aligns with the control scheme. Verify thermal performance within the operating temperature range for the intended application environment.
Part Context
The RT8470 series belongs to Richtek's portfolio of power management integrated circuits focused on LED driving solutions. These components typically integrate power switches and control logic to simplify design. The GJ5 suffix denotes a specific package variant, often associated with small outline transistor packages suitable for automated surface-mount assembly processes.
Replacement Considerations
Consult official Richtek substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully. Generic equivalents may not match the specific dimming control or voltage ratings.
