The LT8650SP features second generation Silent Switcher architecture to minimize EMI emissions while delivering high efficiency at high switching frequencies. This includes integrationofbypasscapacitorstooptimizehighfrequency current loops and make it easy to achieve advertised EMI performancebyeliminatinglayoutsensitivity.Thetopofthe package features exposed die for heat sink attach which is required to meet maximum output current ratings. Thefast,clean,low-overshootswitchingedgesenablehigh efficiency operation even at high switching frequencies, leading to a small overall solution size. Peak current mode control with a 40ns minimum on-time allows high step down ratios at high switching frequencies. Burst Mode operation features a 6.2μA quiescent current resulting in high efficiency at low output currents, forced continuous mode allows fixed switching frequency opera- tionovertheentireoutputloadrange,andspreadspectrum operation can further reduce EMI emissions. External VC pins allow optimal loop compensation for fast transient response. The VC pins can also be used for current sharing andtheCLKOUTpinenablessynchronizingtwoLT8650SP chips to generate a 4-phase, 24A supply.
