19-3165; Rev 0; 1/04 KIT ATION EVALU E L B AVAILA .. Dual, Interleaved, Fixed-Frequency Step-Down Controller with a Dynamically Adjustable Output General Description The MAX1549 dual pulse-width modulation (PWM) stepdown controller provides the high efficiency, excellent transient response, and high DC-output accuracy necessary for generating low-voltage chipset and RAM power supplies in notebook puters. The controller employs a fixed-frequency, current-mode PWM architecture that does not require plex pensation. The MAX1549 also interleaves the dual step-down regulators, minimizing the input capacitor requirements. The MAX1549 Features differential...
