Linear Technology Corporation announces the LT3972, a 3.5A, 33VIN step-down switching regulator with Burst Mode operation to keep quiescent current under 75uA. The LT3972 operates within a VIN range of 3.6V to 33V, with overvoltage lockout protection against transients as high as 62V, making it ideal for load dump and cold-crank conditions commonly found in automotive applications. Its internal 4.6A switch can deliver up to 3.5A of continuous output current at voltages as low as 0.79V |

SUNNYVALE, CA 17, 2008 Maxim Integrated Products (Pink Sheets: MXIM) introduces the MAX8655, the first switching, step-down regulator to incorporate the MOSFETs and to shrink regulator packaging into the industry's smallest footprint an 8mm x 8mm x 0.8mm (height) TQFN. This device provides output currents of up to 25A. A wide 4.5V to 25V input-voltage range allows for internal bus architecture (IBA) applications, where input voltage can have a two-to-one variation. A breakthrough in power density, output current, and size, the MAX8655 is ideal for any application in which space, power, and versatility are crucial. |
