Overview
The TPS61062DRBR is a Texas Instruments LED lighting driver IC featuring a boost topology. It provides a constant current output of 400 mA with a maximum output voltage of 24 V. The device operates within an input voltage range of 2.7 V to 6 V and utilizes a fixed switching frequency of 1 MHz. It supports PWM dimming for brightness control and is housed in an 8-pin VSON (DRB) package. The component functions reliably across a temperature range of -40°C to +85°C.
Feature Summary
- Integrates digital and PWM brightness control capabilities for precise LED regulation.
- Utilizes a compact 8-pin VSON surface-mount package design.
- Supports high-frequency operation to minimize external passive component size.
Applications
- LED backlight drivers
- Portable electronic devices
- General LED illumination systems
Procurement Notes
Verify the specific suffix DRB corresponds to the required 8-pin VSON packaging configuration. Confirm that the 24V output rating aligns with the target LED string requirements, as this distinguishes it from similar variants like the TPS61060. Ensure compatibility with the intended operating temperature range of -40°C to +85°C for the final application environment.
Selection Notes
Select this component when a boost converter is needed for single-channel LED driving with integrated dimming controls. The 400mA output current suits medium-power LED strings. Consider the 1MHz switching frequency for board space constraints. Verify input voltage stability between 2.7V and 6V before implementation.
Part Context
This part belongs to the TPS6106x family of constant current LED drivers from Texas Instruments. These devices are engineered for portable applications requiring efficient power management. The TPS61062 variant specifically offers higher output voltage capability compared to lower-voltage counterparts in the same series.
Replacement Considerations
The TPS61060DRBR serves as a functional substitute if the application requires a lower maximum output voltage of 15V instead of 24V. Both share identical pinouts, control interfaces, and packaging.
