7.1 Overview

The TPSM846C24 device is a 35-A, high-performance, synchronous buck power module, enabling high-power density and minimal PCB area. This device implements the industry-standard fixed switching frequency, voltage-mode control with input feed-forward topology that responds instantly to input voltage change. The TSPM846C24 device can be synchronized to the external clock to eliminate beat noise and reduce EMI and EMC. Monotonic prebias capability eliminates concerns about damaging sensitive loads. Two TPSM846C24 devices can be paralleled together to provide up to 70-A load. Current sensing for overcurrent protection and current sharing between two devices are implemented by sampling a small portion of the power-stage current which provides accurate information independent of the device temperature.
