LM27403 Synchronous Buck Controller

Texas Instruments LM27403 Synchronous Buck Controller offers exceptional levels of integration and performance for superior efficiency in high power density, point-of-load (PoL) DC-DC regulator solutions. The resistor-programmable switching frequency from 200kHz to 1.2MHz and integrated, high-current MOSFET gate drivers with adaptive deadtime offer flexibility to optimize solution size and maximize conversion efficiency. High precision and low output voltage are easily obtained with a 0.6V, 1% accurate voltage reference together with a 30ns high-side MOSFET minimum controllable on-time. Using lossless inductor DC resistance (DCR) current sensing and an inexpensive 2N3904 BJT to sense temperature remotely at the inductor, the LM27403 supports accurate and thermally-compensated overcurrent protection (OCP).
