10 pcs : LM27403SQE/NOPB - Switching Controllers High Perf Sync Buck Cntlr

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).
