Procurement Notes

This product is officially listed as obsolete and no longer manufactured by Toshiba Semiconductor and Storage. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or secondary market suppliers. Buyers must confirm the specific ordering suffix and package condition, as availability varies. Due to the discontinued status, lead times and pricing are not guaranteed by the manufacturer. Ensure that any sourced units match the original specifications before integration into new designs.

Selection Notes

Select this component only if the design requires a single-channel boost LED driver with PWM dimming capability. Verify that the input voltage range of 2.8V to 5.5V aligns with the system power supply. The 20mA output current limit defines the maximum LED load capacity. Consider the SOT-23-6 package size for space-constrained layouts. Since the part is obsolete, evaluate alternative components from the same manufacturer family or other vendors that offer similar electrical characteristics and pin compatibility for long-term production viability.

Part Context

The TB62752AFUG,EL belongs to the TB62752 series of LED driver integrated circuits. This series focuses on providing efficient power management for small-scale LED arrays. The specific model integrates necessary control logic and power stages into a minimal footprint.
