LTC3835 very low quiescent current step-down dc/dc synchronous controller from Linear Technology draws just 80ìA in sleep mode, preserving battery energy in applications, such as automotive navigation or battery-powered monitoring devices where the system remains semi-active when the engine or power is off. Input supply range of 4 to 36 V protects against high-input voltage transients and continues to operate during a cold crank condition. Controller comes in two versions. LTC3835 offers PolyPhase operation for current sharing multiple ICs for delivery of higher output current. It is offered in 20-lead TSSOP and 4 x 5 mm QFN packages. LTC3835-1 is housed in a smaller 16-pin SSOP and 5 x 3 mm QFN packages.
