TPS61060YZFR

Overview

The TPS61060YZFR is a Texas Instruments LED lighting driver IC featuring a boost converter topology. It operates with 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 provides a regulated output voltage up to 15 V (specifically 14.5 V). It utilizes an 8-DSBGA package and functions within a temperature range of -40°C to +85°C. Key features include PWM dimming capability and constant current output control for white LED power supplies.

Feature Summary

• Integrated boost converter topology designed for step-up DC-DC regulation
• Supports PWM dimming for brightness control applications
• Provides constant current output for stable LED driving
• Compact surface-mount packaging suitable for space-constrained designs

Applications

• White LED backlight power supplies
• Portable electronic device illumination systems
• General LED lighting driver circuits

Procurement Notes

Verify the specific ordering suffix matches the required package variant, as the TPS61060 series includes different packages such as DSBGA and SON. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure the supplier provides official datasheets matching the exact part number to avoid compatibility issues with design specifications.

Selection Notes

Select this component when designing circuits requiring a compact boost converter for white LEDs with input voltages between 2.7 V and 6 V. Consider the 1 MHz switching frequency for inductor size optimization. Evaluate the 400 mA output current limit against load requirements. Verify that the 8-DSBGA package footprint aligns with PCB layout constraints and thermal management needs.

Part Context

This part belongs to the TPS61060 family of LED drivers from Texas Instruments. It shares functional similarities with other members like the TPS61060DRBR but differs in physical packaging. The YZFR suffix specifically denotes the DSBGA-8 package configuration, distinguishing it from SON-based variants within the same electrical specification family.

Replacement Considerations

The TPS61060DRBR serves as a related alternative within the same product family, offering identical electrical specifications but utilizing a SON-8 package instead of DSBGA-8. Designers must verify pinout compatibility and thermal performance differences when substituting between these package types.
