LT8648SJV#PBF

LT®8648S synchronous step-down regulator features second generation Silent Switcher architecture designed to minimize EMI emissions while delivering high efficiency at high switching frequencies. This includes the integration of input and boost capacitors to optimize all the fast current loops inside and make it easy to achieve advertised EMI performance by reducing layout sensitivity. This performance makes this ideal for noise sensitive applications and environments. The fast, clean, low overshoot switching edges enable high efficiency operation even at high switching frequencies, leading to a small overall solution size. Peak current mode control with a 25ns minimum on-time allows high step down ratios even at high switching frequencies. External compensation via the VC pin allows for fast transient response at high switching frequencies. Typical applications are industrial supplies, general purpose step-down.

• Ultralow EMI emissions on any PCB, eliminates PCB layout sensitivity
• Internal bypass capacitors reduce radiated EMI, high efficiency at high frequency
• Low quiescent current Burst Mode® operation, forced continuous mode
• External compensation: fast transient response and current sharing
• Output soft-start and power good, safely tolerates high reverse current
• Minimum input voltage is 2.6V max (fSW=400KHz, TA=25°C)
• VIN quiescent current in shutdown is 9µA max (VEN/UV=0V, VIN=12V)
• Feedback reference voltage is 0.602V max (VIN=12V)
• LQFN (laminate package with QFN footprint) package
• Temperature rating range from -40°C to 150°C
