MAX728 Datasheet (Maxim) - 5V/3.3V/3V 5A Step-Down / PWM / Switch-Mode DC-DC Regulators

MAX728, 5V/3.3V/3V 5A Step-Down / PWM / Switch-Mode DC-DC Regulators

The MAX787/MAX788/MAX789 are monolithic, bipolar, pulse-width modulation (PWM), switch-mode, step-down DC-DC regulators.

Each is rated at 5A.

Very few external components are needed for standard operation because the power switch, oscillator, feedback, and control circuitry are all on-chip.
