The LT8650S, a new step-down regulator from Analog Devices, provides high-efficiency operation at high switching frequencies. It features Silent Switcher® technology, eliminating layout sensitivity and reducing EMI emissions.
The LT8650S combines high efficiency at high frequencies and an ultralow EMI design to deliver a very compact dual output 4 A (6 A peak) synchronous step-down solution. It delivers efficiency as high as 94.4% (12 VIN to 5 VOUT) with a switching frequency of 2 MHz offering a very compact solution footprint. The LT8650S’s unique Silent Switcher® 2 architecture uses four internal input capacitors as well as internal BST and INTVCC capacitors to minimize the area of the hot loops. Additionally, its fast, clean, low overshoot switching edges enable high-efficiency operation, high switching frequencies, and low EMI/EMC emissions. LT8650S can easily pass the automotive CISPR 25, Class 5 peak EMI limits with a 2 MHz switching frequency over its entire load range.
