MAX787ECK

5V / 3.3V / 3V 5A降压型， PWM ，开关模式DC- DC稳压器 5V/3.3V/3V 5A Step-Down, PWM, Switch-Mode DC-DC Regulators

General Description

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. Employing a classic buck topology, these regulators perform high-current step-down functions.
