MAX726ECK中文资料美信数据手册PDF规格书

General Description

The MAX724/MAX726 are monolithic, bipolar, pulsewidth modulation (PWM), switch-mode DC-DC regulators optimized for step-down applications. The MAX724 is rated at 5A, and the MAX726 at 2A. Few external components are needed for standard operation because the power switch, oscillator, and control circuitry are all on-chip. Employing a classic buck topology, these regulators perform high-current stepdown functions, but can also be configured as inverters, negative boost converters, or flyback converters.
