The ADPL®74101 is a high-performance step-down DC-to-DC controller that drives all N-channel synchronous metal-oxide-semiconductor field-effect transistor (MOSFET) power stages from input voltages up to 100V.
The ADPL74101 features an adjustable gate-drive voltage from 4V to 5.5V, ideal for driving logic-level MOSFETs.
The internal smart bootstrap switch avoids the need for an external diode. The very low no-load quiescent current extends operating runtime in battery-powered systems. The MODE pin selects among Burst Mode operation, pulse-skipping mode, or continuous inductor current mode at light loads.
The ADPL74101 additionally features spread spectrum operation, which significantly reduces the peak radiated and conducted noise on both the input and output supplies, making it easier to comply with electromagnetic interference (EMI) standards.
