- use smaller batteries in their design. For example, designers can save up to 16,980 mm3 using four AAAs instead of four AAs.
- Flexible VIN broadens applications: The TPS62840's wide range of 1.8 VIN-6.5 VIN accommodates multiple battery chemistries and configurations, such as two lithium manganese dioxide (2s-LiMnO2) cells in series, single-cell lithium thionyl chloride (1xLiSOCL2), four-cell and two-cell alkaline, and lithium polymer (Li-Po).
Pre-production samples of the TPS62840 are available through the TI store in the following packages: eight-pin small outline no-lead (SON), measuring 1.5 mm by 2.0 mm; six-pin wafer chip scale package (WCSP), measuring 0.97 mm by 1.47 mm. An eight-pin thermally enhanced package (HVSSOP), measuring 3 mm by 5 mm, will become available later this year.
Pricing starts at $0.85 in 1,000-unit quantities. The TPS62840-1DLCEVM55 and TPS62840-1YBGEVM56 evaluation modules are available for $49 each.
