2a Step-down Switching Regulator

  The LD7412 is a high efficiency asynchronous buck converter with a constant-frequency, and voltage-mode architecture. It achieves 2A continuous output current over a wide input voltage ranging from 4.3V to 18V. The IC provides a feed forward voltage mode operation to achieve the fast line-transient response. The LD7412 also provides soft-start function to prevent overshoot during startup. Fault condition protections include cycle-by-cycle current limiting and hiccup overload protection, which can reduce the operation frequency from 400kHz to 50kHz. The LD7412 minimizes the number of external components to complete a 2A Step-down DC-DC converter solution.
