High Voltage Isolated Monolithic Flyback Regulator Simplifies Design & Eliminates Optocoupler
Linear Technology announced the LT3512, a high voltage isolated monolithic flyback regulator that significantly simplifies the design of an isolated DC/DC converter. No optocoupler, third winding or signal transformer is required for feedback since the output voltage is sensed from the primary-side flyback signal. The LT3512 operates over a 4.5V to 100V input voltage range, has a 420mA, 150V power switch and delivers up to 4.5 watts of output pow...
-55°C to 125°C Buck-Boost DC/DC uModule Regulator, up to 36VIN, 34VOUT & 98% Efficiency
Linear Technology introduced the LTM4609MP, a buck-boost DC/DC uModule® system-in-a-package that is guaranteed and tested for the wide -55°C to 125°C temperature range. The LTM4609MP is designed to deliver precision regulation in demanding environments in applications such as military, avionics, heavy industrial machinery, and harsh environment sensors. These uModule devices are backed by Linear Technology's rigorous reliability and quality t...
Vitreous-enamelled resistors toughen up modern electronic controls
Welwyn Components W20 series vitreous enamelled wirewound resistors are said to deliver rugged, dependable power handling for automotive electronics and other equipment used in harsh or hostile environments. These resistors benefit from a proprietary lead free vitreous enamel coating, which requires no flame-retardant additives and provides superior environmental protection. They can be used in products meeting strict regulations on disposal, su...
Ultra Small Resistors from TTI Europe
TTI Europe has announced a low-value current sense surface mount chip resistor family, recently launched by TT Electronics Welwyn Components. Complementing the existing LR series, the new devices are available in three smaller sizes - 0805, 0603 and 0402 - whilst retaining the same thick-film on ceramic construction. This saves space on circuit boards, enabling miniaturisation and providing increased choice for product designers.
