Beschreibung

KI-Übersetzung

The LTC7852/LTC7852-1 is a six-phase, dual output current mode synchronous step-down switching regulator controller that works in conjunction with external power train devices such as DrMOS, power blocks or discrete N-channel MOSFETs and associated gate drivers. Its flexible design enables 1-, 2-, 3-, 4-, 5-, and 6-phase configurations. The LTC7852 offers a unique feature that enhances the signal-to-noise ratio of the current sense signal, allowing the use of inductors with very low DC winding resistances for maximum efficiency. The controller achieves a minimum on-time of just 40ns, permitting the use of high switching frequency at high step-down ratios. 8-, 10- or 12 phases with two ICs can be paralleled for very high current requirements up to 400A. The remote sense differential amplifiers and a precise reference provide accurate output voltages between 0.5V and 2.0V. The input voltage is not limited by the controller. Hiccup mode protection from output shorts or overcurrent minimizes the thermal dissipation. The LTC7852-1 is designed specifically for DrMOS with an internal current sense signal.
