Overview
The TPS61062YZFT is a constant current LED driver IC from Texas Instruments, utilizing a boost converter topology. It operates within an input voltage range of 2.7 V to 6 V and delivers a maximum output current of 400 mA. The device supports a switching frequency of 1 MHz and features digital and PWM brightness control capabilities. Designed for SMD/SMT installation, it is housed in an 8-DSBGA package. The component functions within a temperature range of -40°C to +85°C and includes load disconnect during shutdown.
Feature Summary
- Integrates digital and PWM brightness control for precise LED intensity management
- Provides constant current output suitable for driving LED loads
- Includes load disconnect functionality during shutdown mode
Applications
- LED lighting systems requiring dimming control
- Portable electronic devices with backlighting applications
- Battery-powered LED drivers
Procurement Notes
Verify the specific suffix YZFT against the manufacturer's official datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure compatibility with the required DSBGA-8 footprint and thermal management strategy. Cross-reference the RoHS status and operating temperature range with your system specifications before finalizing procurement decisions.
Selection Notes
Select this component when a compact boost converter solution is needed for LED applications with input voltages up to 6 V. Consider its 1 MHz switching frequency for smaller external passive components. Evaluate the 400 mA output limit against your LED string requirements. Verify that the DSBGA-8 package fits within your PCB layout constraints and thermal design goals.
Part Context
This part belongs to the TPS61062 series of LED lighting driver ICs manufactured by Texas Instruments. It is designed as a step-up (boost) converter specifically optimized for driving LEDs from single-cell lithium-ion batteries or other low-voltage sources. The series offers integrated power switches and control logic to simplify circuit design.
Replacement Considerations
Check the TPS61062 datasheet for direct pin-to-pin compatible alternatives within the same family. Verify if variants like TPS61060 offer similar performance with different feature sets. Confirm that any substitute maintains the required 400 mA output current and 1 MHz switching frequency.
