MAX1972EEE+T General Description

The MAX1972EEE+T is a high-performance dual-output current-mode PWM buck regulator that offers exceptional efficiency and reliability. With an input voltage range of 2.6V to 5.5V, this regulator can deliver a minimum of 750mA on each output, ensuring stable power delivery for your system. The fixed switching frequency of 1.4MHz (or 700kHz for the MAX1971) helps to reduce the size and cost of the output inductor and capacitor, making it a cost-effective solution for power management. By operating the regulators 180° out-of-phase, the input capacitor size and cost are minimized, further improving overall efficiency. With the option to use ceramic capacitors for input and output, the MAX1972EEE+T offers a high level of flexibility and performance for your design needs
