Product Summary
The MAX727ECK is a monolithic, bipolar, pulse-width modulation (PWM), switch-mode, step-down DC-DC regulator. Each is rated at 2A. 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, the MAX727ECK performs high-current step-down functions. The applications of the MAX727ECK include Distributed Power from High-Voltage Buses, High-Current, High-Voltage Step-Down Applications, and Multiple-Output Buck Converter.
