Farnell announces PMICs and modules from Analog Devices
Distributor, Farnell is now supplying the latest Analog Devices power products, including what is believed to be the industry’s only 6A automotive buck boost converter, available from stock. These high performance power management ICs (PMICs) and converters meet stringent power requirements.
According to Analog Devices (ADI) these products offer designers “unmatched power densities, ultra low noise technology and superior reliability” which “ensure that systems can operate at optimal efficiency while reducing cost of ownership”.
The ADI power range is supported with a design tool suite and customisable power interconnects.
Among the new additions to the Farnell line card is the MAX25239 / MAX25240 small footprint automotive 2V to 36V, 6A buck boost converters, claimed to be the industry’s only 6A automotive buck-boost with integrated H-bridge switches. The two converters provide a fixed output regulation voltage and an externally adjustable output voltage from 3V to 20V. Input voltage is above, below, or equal to the output regulation voltage. Applications include ADAS ECU (advanced driver assistance systems, engine control units), body electronics, infotainment systems, PoL (point of load) power supplies and start-stop systems.
The distributor also offers the MAX25240 evaluation (EV) kit which provides an assembled and tested application circuit that simplifies the evaluation of the MAX25240 400MkHz, 36V buck boost converter. The standard EV kit comes with the MAX25240AFFF / VY+ installed (11.5V, 400kHz) and can also be used to evaluate other MAX25240 variants. Various test points and jumpers are included for evaluation, and all installed components are rated for the automotive temperature range.
Also included is the LT8355-1 60V in / 120V out dual channel DC/DC controller which is designed to drive two strings of high current LEDs. The fixed frequency, current mode architecture provides stable operation over a range of supply and output voltages, making it possible for the converters to operate as constant voltage sources. Other features, such as exponential PWM and scalable dimming, allow customers to precisely control LED brightness levels. The LT8355-1 is designed for high voltage LED applications, for example automotive head lamps and accurate current limited voltage regulator
There is also the DC3230A featuring the LTM4652. The high efficiency, bi-directional dual-phase μModule regulator is configured as a single 32A, -5V output device. Available in a thermally enhanced 144-lead (16 x 16 x 4.92mm) BGA package, the LTM4652’s temperature sensing options are included via onboard circuit.
Finally, the LT7200S quad-channel, monolithic synchronous buck regulator is capable of sinking / sourcing 5A to the load per channel. Its multi-channel flexibility can power complex systems, said Farnell. Operating voltage range is 2.9V to 18V. It uses second-generation silent switcher technology with integrated bypass capacitors to operate at high frequencies with EMI performance. The LT7200S is suitable for distributed power systems, server power and point of load supply for ASICs and FPGAs, said Farnell.
The Analog Devices power management ICs and power modules are now in stock at Farnell in EMEA, Newark in North America and element14 in APAC.
