Product Description

The MAX1980 step-down slave controller is intended for low-voltage, high-current, multiphase DC-DC applications. The MAX1980 slave controller can be combined with any of Maxim's Quick-PWM™ step-down controllers to form a multiphase DC-DC converter. Existing Quick-PWM controllers, such as the MAX1718, function as the master controller, providing accurate output-voltage regulation, fast transient response, and fault protection features. Synchronized to the master's low-side gate driver, the MAX1980 includes the Quick-PWM constant on-time controller, gate drivers for a synchronous rectifier, active current balancing, and precision current-limit circuitry.

The MAX1980 provides the same high-efficiency, ultra-low duty factor capability, and excellent transient response as other Quick-PWM controllers. The MAX1980 differentially senses the inductor currents of both the master and the slave across current-sense resistors. These differential inputs and the adjustable current-limit threshold derived from an external reference allow the slave controller to accurately balance the inductor currents and provide precise current-limit protection. The MAX1980's dual-purpose current-limit input also allows the slave controller to automatically enter a low-power standby mode when the master controller shuts down.

The MAX1980 features a driver-disable mode that forces both gate drivers (DL and DH) low. While the MAX1980's drivers are disabled, the master controller can operate in low-power skip mode, improving light-load efficiency. Additionally, the MAX1980 includes selectable trigger polarity, allowing the slave controller to trigger on the rising (out-of-phase) or falling (in-phase) edge of the master's low-side gate driver. Out-of-phase operation staggers the master and slave's on-times, reducing the input ripple current and consequently the number of input capacitors. The MAX1980 also features a selectable 200kHz/300kHz/550kHz switching frequency. The MAX1980 is available in compact 20-pin 5mm x 5mm QFN and thin QFN packages
