The MAX8543/MAX8544 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/MAX8544 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/MAX8544 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 MAX8544 features a power-OK monitor and two MAX8544 controllers that can operate at 180° out-of-phase for dual-output applications.
