TPS62840DLCR FAQ

What is the current of the TPS62840?

60 nA.

What is the TPS62840?

High-efficiency step-down converter.

What does the TPS62840 achieve in 100% mode?

120 nA IQ.

What are switching voltage regulators?

A switching regulator is a voltage regulator that uses a switching element to transform the incoming power supply into a pulsed voltage, which is then smoothed using capacitors, inductors, and other elements.

How do switching voltage regulators work?

A switching regulator can convert input direct current (DC) voltage to the desired direct current (DC) voltage. In an electronic or other device, a switching regulator takes the role of converting the voltage from a battery or other power source to the voltages required by subsequent systems.
