Description
The LT3991EDD#PBF is a DC switching regulator used to control and regulate the voltage of electronic devices. It accepts a wide input voltage range up to 62V and consumes only 2.5µA of quiescent current. The LT3991EDD#PBF features low ripple Burst Mode operation which maintains high efficiency at low output currents, while keeping the output ripple below 5mV in a typical application. It uses a current mode topology for fast transient response and good loop stability and has an accurate programmable undervoltage lockout feature producing a low shutdown current of 0.7µA.
