MAX724 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.
These regulators have excellent dynamic and transient response characteristics, while featuring cycle-by-cycle current limiting to protect against overcurrent faults and short-circuit output faults. The MAX724/MAX726 also have a wide 8V to 40V input range in the buck stepdown configuration. In inverting and boost configurations, the input can be as low as 5V.
The MAX724/MAX726 are available in a 5-pin TO-220 package. The devices have a preset 100kHz oscillator frequency and a preset current limit of 6.5A (MAX724) or 2.6A (MAX726)
