1 / 11 page Page No. : 1/11 RS6515 2A, 20V, 400KHz DC/DC Asynchronous Step‐Down Converter General Description The RS6515 is a high‐efficiency asynchronous step‐down DC/DC converter that can deliver up to 2A output current from 4.75V to 20V input supply. The RS6515's current mode architecture and external compensation allow the transient response to be optimized over a wide range of loads and output capacitors. Cycle‐by‐cycle current limit provides protection against shorted outputs and soft‐start eliminates input current surge during start‐up. The RS6515 also provides output under voltage protection and thermal shutdown protection. The low current (<30μA) shutdown mode provides output disconnection, enabling easy power management in battery‐powered systems. Features Applications ● 2A Output Current ● Up to 93% Efficiency ● Integrated 100mΩ Power MOSFET Switches ● Fixed 385KHz Frequency ● Cycle‐by‐Cycle Over Current Protection ● Thermal Shutdown function ● Wide 4.75V to 21V Operating Input Range ● Output Adjustable from 0.92V to 18V ● Programmable Under Voltage Lockout ● Available in an MSOP‐10(EP) Package ● RoHS Compliant and 100% Lead (Pb)‐Free and Green (Halogen Free with Commercial Standard) ● PC Motherboard, Graphic Card ● LCD Monitor ● Set‐Top Boxes ● DVD‐Video Player ● Telecom Equipment ● ADSL Modem ● Printer and other Peripheral Equipment ● Microprocessor core supply ● Networking power supply ● Pre‐Regulator for Linear Regulators ● Green Electronics/Appliances Application Circuits INPUT ON OUTPUT C5 10nF C1 10uF/35V C4 0.1uF R3 5.6KΩ C3 8.2nF C6 (Optional) D1 B340A U1 RS6515‐ADMS 4 5 10 7 6 9 8 IN SW SS FB GND EN COMP R1 25.8KΩ 1% L1 15uH R2 10KΩ 1% C2 22uF/6.3V OFF 4.75V to 21V CERAMIC x2 3.3V/2A CERAMIC x2 This integrated circuit can be damaged by ESD. Orister Corporation recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
