... The LTC1516 operates as either a doubler or a tripler depending on V overall efficiency. The part has thermal shutdown and can survive a continuous short from V down the load is disconnected from V The LTC1516 is available in an 8-pin SO package in both commercial and industrial temperature grades. , LTC and LT are registered trademarks of Linear Technology Corporation. 0. – ...

... COMP2 and the charge pump is disabled. When the charge pump is disabled, the LTC1516 draws only 8 A (typ) from V which provides high IN efficiency at low load conditions. To achieve the highest efficiency over the entire V the LTC1516 operates as either a doubler or a tripler 4 S2A S2B COMP1 CLOCK 1 COMP2 ...

... Figure 4a. No Load I vs Input Voltage for Circuit in Figure The LTC1516 must be out of shutdown for a minimum duration of 200 s to allow enough time to sense the output and keep it in regulation. As the V increases, the frequency with which the part is taken out . OUT of shutdown must also be increased to prevent V from drooping below 4 ...

... U U APPLICATIONS INFORMATION Paralleling Devices Two or more LTC1516’s may be connected in parallel to provide higher output currents. The V SHDN pins may be tied together, but the C1 and C2 pins must be kept separate (see Figure 5). Separate C C capacitors may be required to reduce output noise OUT and ripple if the paralleled devices cannot be kept close together ...
