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 |
