The LT3680IDD#PBF is a monolithic buck switching regulator designed for applications requiring efficient voltage conversion. It accepts input voltages from 3.6V up to 36V and can deliver a maximum output current of 3.5A. The device operates with an adjustable switching frequency, ranging from 200kHz to 2.4MHz, allowing for optimization of efficiency and component size.
Key features include a low quiescent current of 75µA in Burst Mode operation and a low shutdown current of less than 0.5µA. The regulator incorporates an integrated boost diode and a saturating switch with 95mΩ on-resistance for high efficiency. It offers a soft-start capability for controlled output voltage ramp-up and a power good flag to signal when the output voltage reaches regulation.
This component is available in a 10-DFN (3x3) package with an exposed pad for enhanced thermal performance. The surface mountable design is suitable for various power management applications, including automotive battery regulation, portable product power, and distributed supply regulation.
The output voltage is adjustable from 0.79V to 30V, with a feedback reference voltage of 0.790V. The LT3680 is designed for good loop stability and fast transient response due to its current mode topology.
