Thermal management and cost of ownership in power systems
by Jerry Hovdestad, Director COTS Engineering, Behlman Electronics To an engineer, power management is also thermal management. Excess heat generated by power systems places additional burdens on their cooling technology. Even the most efficient system will have performance and reliability issues if served by an inefficient cooling method. Power and heat are two sides of […]
Buck dc/dc converter provides 8 A for four outputs
Linear Technology Corporation announces the LTC3371, a highly integrated general-purpose power management solution for systems requiring multiple low voltage power supplies. The device features four synchronous buck converters, each powered from independent 2.25V to 5.5V inputs, and each configurable to share up to four of eight available 1A power stages. With eight unique output current […]
20-A step-down regulator optimized for low V IN/low V OUT
Linear Technology Corporation introduces the LTM4639, a 20A DC/DC step-down µModule® (micromodule) regulator capable of converting 2.5V to 7V main-power system rails to point-of-load voltages as low as 0.6V with optimum efficiency.
