60V Input Dual Output Synchronous Step-Down DC/DC Controller
Linear Technology Corporation introduces the LTC3890/-1, a high voltage dual output synchronous step-down DC/DC controller that draws only 50µA when one output is active and 60µA when both outputs are enabled. With both outputs shut down, the LTC3890/-1 draws a mere 14µA. The 4V to 60V input supply range is designed to protect against high voltage transients, continue operation during automotive cold crank and cover a broad range of input sour...
