Overview
The STLD20D-C8 is a white LED power supply and driver IC from STMicroelectronics, designed for high-speed and low-voltage operations. It features a step-up (boost) DC-DC regulator architecture with a switching frequency of 500kHz. The device supports both analog and PWM dimming methods to control LED brightness. It operates within a supply voltage range of 2.5V to 5V and delivers an output current of 21mA. The component is housed in a surface-mount SOT-23-8 package and functions reliably across an operating temperature range of -40°C to 85°C.
Feature Summary
- Integrated step-up DC-DC regulator optimized for low-voltage applications
- Supports dual dimming modes including analog and PWM control
- High-speed switching operation at 500kHz for efficient power management
Applications
- LED backlighting systems
- White LED power supplies
- Low-voltage portable electronic devices
Procurement Notes
Verify the specific ordering code against official STMicroelectronics documentation to ensure correct package selection. Confirm that the SOT-23-8L marking matches the required physical footprint. Check for tape and reel packing specifications if automated assembly is intended. Ensure environmental compliance requirements align with project standards before finalizing procurement.
Selection Notes
Select this component when a compact boost converter solution is needed for single-output white LED driving. Consider the 2.5V to 5V input range compatibility with system power rails. Evaluate the 500kHz switching frequency against EMI constraints and inductor size requirements. Verify that the SOT-23-8 package fits within the available PCB area constraints.
Part Context
This part belongs to the STLD20D series of LED drivers manufactured by STMicroelectronics. The series includes variants such as the STLD20D-DEF which utilizes a QFN package. The C8 suffix specifically denotes the SOT-23-8 surface mount configuration. This family targets general lighting and display backlighting applications requiring efficient regulation.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other STMicroelectronics LED driver families only if pinout and electrical parameters match exactly.
