TPS62300




















 
 

The TPS62300 3-MHz, 500-mA DC/DC converter offers 93% peak efficiency and -0.5% to 1.3% voltage regulation accuracy in an ultra-small 2 mm x 1 mm chip-scale package that is extremely reliable, lead (Pb)-free and green*. The smallest inductor size (1 µH), integrated FETs and chip-scale packaging result in the industry’s smallest, most efficient, high-accuracy step-down DC/DC solution for space-constrained, battery-powered applications.

* TI defines "Lead (Pb)-Free" or "Pb-Free" to mean RoHS compatible, including a lead concentration that does not exceed 0.1% of total product weight, and, if designed to be soldered, suitable for use in specified lead-free soldering processes. TI defines “Green” to mean Lead (Pb)-Free and in addition, uses package materials that do not contain halogens, including bromine (Br), or antimony (Sb) above 0.1% of total product weight.
