DC/DC converters target rail, telecoms applications

DC/DC converters target rail, telecoms applications
Murata’s RUW15 Series DC/DC convertors are now available at TTI. Suited for rail, industrial and telecommunications applications, where variable input voltages or high transient voltages are present, the converters are capable of withstanding surges from 24V, 36V, 48V, 72V, 90V and 110V systems, largely eliminating the need for input protection circuitry.

Controller gently powers up board capacitors

Controller gently powers up board capacitors
The LTC4231, a quiescent current (IQ) controller which enables safe board or battery insertion and extraction, has been released by Linear Technology. To gently power up 2.7-36V systems, the device controls an external N-channel MOSFET, avoiding sparks, connector damage and system glitches. During normal operation quiescent current is 4µA, dropping to 0.3µA in shutdown mode.
