The stop pin can be used to completely interrupt switching to reduce electromagnetic interference or ripple and to minimize distortion on precise signal chain devices, sensors, or radio transmission devices.
Developers can use the new switching regulator to manage with half the batteries or use smaller batteries in their design. For example, using four AAA batteries instead of four AA batteries can save up to 16.98 cc.
The wide input voltage range of the TPS62840, from 1.8V to 6.5V, is suitable for various battery chemistries and configurations, such as two lithium manganese dioxide cells in series (2s-LiMnO2), one lithium thionyl chloride cell (1xLiSOCL2), four or two alkaline cells, or lithium polymer batteries (Li-Po).
