Demonstration circuit 2866A features the LTC4421 Dual Supply High Power Prioritized Powerpath™ Controller in a 12V/24V, 10A application. The LTC4421 incorporates strong gate drivers to switch large external N-channel MOSFETs and fast switchover circuitry to minimize VOUT droop while preventing reverse and cross conduction currents, making it an ideal solution for high reliability systems, battery back up systems, and servers. DC2866A arbitrates between two input supply rails, selecting the highest priority, valid supply to power the load. By definition, the supply connected to V1 is the higher priority supply, although it can be changed dynamically. External resistive dividers set the undervoltage and overvoltage thresholds that bound the valid voltage window. External sense resistors set the limit on maximum current that can flow to the load. Two or more DC2866As can be cascaded to provide switchover between more than two rails.

The LTC4238 is a high voltage high current Hot Swap controller that allows a board to be safely inserted and removed from a live backplane. Dual 12V gate drive is well suited for high power applications to either share safe operating area across parallel MOSFETs or support a 2-stage start-up that first charges the load capacitance followed by enabling a low on-resistance path to the load.The device features active current limiting (ACL) with two foldback options as VDS increases. The constant power profile limits the power dissipation to be no higher than a fixed value, while the high power profile allows the part to ride through large input steps during operation.The LTC4238 notifies when output power is good. In addition, it has protection features that respond to input undervoltage, overvoltage; and generate a fault when there is an overcurrent or FET bad condition.Applications Live Board Insertion in 12V, 24V and 48V Systems Industrial High Side Switch/Circuit Breaker Computers, Servers Vehicle Electrical Systems

The LTC7802 is a high performance dual step-down synchronous DC/DC switching regulator controller that drives all N-channel power MOSFET stages. Constant frequencycurrent mode architecture allows a phase-lockable switching frequency of up to 3MHz. The LTC7802 operates from a wide 4.5V to 40V input supply range. Power loss and supply noise are minimized by operating the two controller output stages out-of-phase.The very low no-load quiescent current extends operating runtime in battery powered systems. OPTI-LOOP compensation allows the transient response to be optimizedover a wide range of output capacitance and ESR values. The LTC7802 features a precision 0.8V reference and power good output indicators. The MODE pin selects among Burst Mode operation, pulse-skipping mode, or continuous inductor current mode at light loads.The LTC7802 additionally features spread spectrum operation which significantly reduces the peak radiated and conducted noise on both the input and output supplies, making it easier to comply with electromagnetic interference (EMI) standards.APPLICATIONSAutomotive and TransportationIndustrialMilitary/Avionics

The LT8638S 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 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 the LT8638S 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. PolyPhase operation allows multiple LT8638S regulators to run with interleaving phase shift to provide more output current.Burst Mode operation enables low standby current consumption, forced continuous mode can control frequency harmonics across the entire output load range, or spread spectrum operation can further reduce EMI emissions. Soft-start and tracking functionality is accessed via the SS pin, and an accurate input voltage UVLO threshold can be set using the EN/UV pin.
