_______________General Description

The MAX830/MAX831/MAX832/MAX833 are monolithic,

bipolar, pulse-width-modulation (PWM), switch-mode, step-

down 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.

These regulators have excellent dynamic and transient

response characteristics, while featuring cycle-by-cycle cur-

rent limiting to protect against overcurrent faults and short-

circuit 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 100kHz oscillator frequency. In addition,

the preset current limit and micropower shutdown can be

externally controlled. See the MAX724/MAX726 data

sheet for more applications information.
