MAX789ECK规格书详情
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.
Features
♦ Input Range: Up to 40V
♦ 5A On-Chip Power Switch
♦ Fixed Outputs: 5V (MAX787)
3.3V (MAX788)
3V (MAX789)
♦ 100kHz Switching Frequency
♦ Excellent Dynamic Characteristics
♦ Few External Components
♦ 8.5mA Quiescent Current
♦ TO-220 Package
Applications
Distributed Power from High-Voltage Buses
High-Current, High-Voltage Step-Down
Multiple-Output Buck Converter
