General Description

The MAX830/MAX831/MAX832/MAX833 are monolithic, bipolar, pulse-width-modulation (PWM), switch-mode, stepdown DC-DC regulators. 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.
