LT8652S/3S Dual-Channel 8.5 A/18 V Step-Down Silent Switcher®

ADI's LT8652S and LT8653S employe dual-channel 8.5 A/18 V step-down Silent Switcher architecture for ultralow electromagnetic interference (EMI) performance. EMI is often a challenge for system designers particularly for applications such as automotive, industrial, and communications systems with stringent CISPR compliance. This requires additional EMI filters to the existing circuitry, cost to PCB revision and delay time to market in order to pass the CISPR EMI compliance. The LT865xS family allows designers to simplify PCB design, reduce design cycle time, and meet CISPR EMI compliance with Silent Switcher 2 architecture while maintaining high-efficiency performance across load range in a compact solution.

Features

• Silent Switcher 2 architecture:
• Internal bypass capacitors reduce radiated EMI
• Ultra-low quiescent current Burst Mode® operation
• High-efficiency at light load and minimize low output ripple voltage (10 mV_pp)
• Small 4 mm x 7 mm 36-pin LQFN with dual 8.5 A output or 17 A combined

Applications

• Communications
• Communication infrastructure applications
• General purpose
• Points of load for server and core power
• Industrial automation
• Building and machine automation
