In summary, the LTC7124 was developed as a higher output current, lower EMI, lower quiescent current version of the successful LTC3633/A buck regulator family. The LTC7124 is a dual channel, 3.5A per output, high efficiency monolithic step-down regulator capable of operating at up to 4MHz from input supplies up to 17V. The regulator features low quiescent current for high efficiency over a wide VOUT range as low as 5.5µA. The LTC7124 includes spread spectrum modulation for low radiated and conductive noise. The LTC7124 is offered in a thermally enhanced, low profile 24-lead 3mm × 5mm QFN package.
