Each is rated at 1A. Very few external components are needed for standard operation because the power switch, oscillator, feedback, and control circuitry are all on-chip. Employing a classic buck topology, these regulators perform high-current step-down functions. These regulators have excellent dynamic and transient response characteristics, while featuring cycle-by-cycle current limiting to protect against overcurrent faults and shortcircuit output faults. They have a wide 8V to 30V input range. Outputs for the MAX831/MAX832/MAX833 are fixed at 5V/3.3V/3V, respectively. The MAX830 output is adjustable. Available in 16-pin SO packages, the MAX830–MAX833 have a preset 10...
