DESCRIPTION The LT?3509 is a dual, current mode, step-down switching regulator, with internal power switches each capable of providing 700mA output current. This regulator provides a compact and robust solution for multi-rail systems in harsh environments. It incorporates several protection features including overvoltage lockout and cycle-by-cycle current limit. Thermal shutdown provides additional protection. FEATURES Two 700mA Switching Regulators with Internal Power Switches Wide 3.6V to 36V Operating Range Overvoltage Lockout Protects Circuit Through 60V Supply Transients Short-Circuit Robust Low Dropout Voltage: 95% Maximum Duty Cycle Adjustable 300kHz to 2.2MHz Switching Frequency Synchronizable Over the Full Range Uses Small Inductors and Ceramic Capacitors ntegrated Boost Diodes nternal Compensation Thermally Enhanced 14-Lead (4mm × 3mm) DFN and 16 Lead MSOP Packages APPLICATIONS Automotive Electronics Industrial Controls Wall Transformer Regulation Networking Devices CPU, DSP, or FPGA Power |
