High-voltage DC/DC convertor delivers to
2A
Operating over a wide 7.5 to 40V input-voltage range, the MAX15020 is ideal for automotive, industrial and printer applications.
Available now from Maxim Integrated Products, the MAX15020 is a high-voltage DC/DC convertor that is capable of delivering up to 2A of output current while operating with switching frequencies up to 500kHz The high switching frequency, along with the integrated high-side switch (0.18ohm), reduces the number and size of external components required by the total solution, thus saving board space and reducing system cost

New from Maxim Integrated Products, the MAX1162 serial-interface 16bit A/D convertor connects directly to SPI, QSPI and Microwire devices without additional interface logic.
Operating over a wide 7.5 to 40V input-voltage range, the MAX15020 is ideal for automotive, industrial and printer applications.
The MAX15020 uses a feed-forward voltage-mode architecture to provide good noise immunity in high-voltage switching environments, and it allows external compensation for increased design flexibility.
This convertor offers internal switching frequencies of 300 and 500kHz, or it can be synchronised to an external clock ranging from 100 to 500kHz.
To maximise flexibility, the MAX15020 allows designers to set the output voltage using two external resistors.
An external reference input also provides the capability of dynamically adjusting the output voltage from 0.5 to 36V.
The MAX15020 provides protection features including configurable undervoltage lockout (UVLO), soft-start, thermal shutdown, cycle-by-cycle current limit, and a hiccup-mode for output short-circuit protection.
To save power during nonoperation, the device offers a shutdown mode that reduces current consumption down to only 6uA.
The MAX15020 is fully specified over the -40 to +125C automotive temperature range and is available in a thermally enhanced, 5 x 5mm, 20-pin TQFN package.
Prices start at US $1.47 (1000-up).
