There are two broad descriptions of machine safeguarding: prevention of contact with the hazard and control of the energy driving the hazardous operation. Machine barrier guarding is a way to avoid contact with a hazard, while lockout/tagout (LOTO) procedures and the use of control reliable circuits are ways to control the energy driving the

In this reference design, a lithium polymer battery is added to the output of the boost converter to absorb the pulse load current and extend the alkaline battery life time. The designed circuit also benefits uninterrupted power supply when the alkaline battery is out of charge. All Design files. TPS61220.
