The MAX1809 is a reversible energy flow, constant-offtime, pulse-width modulated (PWM), step-down DC-DC converter.

an internal PMOS power switch and internal synchronous rectifier for high efficiency and reduced component count. The internal 90m Ω PMOS power switch and 70mΩ NMOS synchronous-rectifier switch easily deliver continuous load currents up to 3A. The MAX1809 accurately tracks an external reference voltage, produces an adjustable output from 1.1V to VIN, and achieves efficiencies as high as 93%. The MAX1809 uses a unique current-mode, constantoff-time, PWM control scheme that allows the output to so.
