Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LM25143QRHARQ1 is a 42V synchronous buck DC/DC controller for high current single or dual outputs. Derived from the wide VIN range controller family, the device features an interleaved stackable peak current mode control architecture that enables simple loop compensation, fast transient response, excellent load and line regulation, and precise current sharing through parallel phases for high output currents.
