MAX8544EEP

The MAX8543/MAX8544EEP current-mode, constant-frequency PWM buck controllers operate from a 3V to 13.2V input supply and generate adjustable 0.8V to 0.9 x VIN output voltages at loads up to 25A. They feature adjustable switching frequency and synchronization for noise-sensitive applications. The MAX8543/MAX8544EEP can start with (or without) a preexisting bias on the output, without discharging the output. This feature simplifies tracking supply designs for core and I/O applications and redundant supply designs. The MAX8543/MAX8544EEP use the DC resistance of the output inductor as the current-sense element for lossless, low-cost current sensing. The current-sense threshold can be set to four discrete levels to accommodate inductors with different DC resistance values. The MAX8544EEP features a power-OK monitor and two MAX8544EEP controllers that can operate at 180° out-of-phase for dual-output applications.Learn More About PowerMind
