Alternatives for TPS53353DQPR
If the TPS53353DQPR becomes unavailable or lead times increase, customers may consider the following related Texas Instruments parts for further evaluation:
TPS53355: A 30-A synchronous buck converter featuring integrated MOSFETs, D-CAP control, and a 1.5-V to 15-V conversion input range. It shares the 0.6-V to 5.5-V output range and 22-pin LSON-CLIP package family, making it a potential candidate for designs requiring higher output current. Its electrical and thermal requirements must be evaluated before substitution.
TPS548B28: A newer 20-A synchronous buck converter featuring D-CAP3 control and differential remote sensing. It supports a 4-V to 16-V input range without external bias, or 2.7 V to 16 V with a 3.13-V to 3.6-V external bias supply. Its 21-pin, 4 × 3 mm VQFN-HR package provides a more compact option for updated power designs. Pinout, bias requirements, and electrical characteristics must be evaluated before substitution.
