High-density DC/DC convertors need no airflow

The 5/12V-input PicoTLynx convertor is designed to provide higher power, higher density and faster transient response in a wide variety of board mounted power applications.

Tyco Electronics has brought out 3 and 6A versions of its 5/12V-input PicoTLynx DC/DC convertor.

The 5/12V-input PicoTLynx convertor is designed to provide higher power, higher density and faster transient response in a wide variety of board mounted power applications.

The 5/12V PicoTLynx convertor series supports a wide input voltage range of 4.5 to 14V and provides a tightly regulated output voltage from 0.59 to 5.5V DC.

The open-frame 3 and 6A modules are available in the same physical size, offering scalable solution for intermediate bus architectures (IBA) in high power density applications.

The 5/12V PicoTLynx convertor offers the same high efficiency as the Lynx series but with significantly improved thermal performance due to innovations in design and packaging.

The 6A PicoTLynx convertor delivers fully rated output current at 75C with no airflow, enabling designers to take advantage of the full power capability of this high-density module.

In addition, standard features include programmable output voltages, remote on/off, remote sense, power good, monotonic startup, overcurrent and overtemperature protection.

The EZ-Sequence feature is available as an option.

The 5/12V PicoTLynx Series convertor also offers the new tunable-loop (patent pending) feature which allows engineers to optimise the control loop to significantly improve transient response and reduce the amount of external filtering.

When the control loop is optimised using the tunable-loop feature, load transient response can be improved up to five-times using identical external capacitance.

The tunable-loop is easy to implement and requires only a minimal set of additional low cost components and no additional pins.

The 5/12V PicoTLynx convertor, currently available in a small SMT package measuring only 12.2 x 12.2 x 6.25mm (3A version), features the LGA interconnect method.

Supporting an industrial operation temperature range of -40 to +85C, the modules meet EU Directive 2002/95/EC RoHS initiatives as well as industry standard board cleaning processes.

"The PicoTLynx convertor, with the patented tunable-loop feature, enables engineers to optimise the module and take advantage of faster transient response for end user applications", says Sabi Varma, General Manager at Tyco Electronics' Power Systems Business.

"We consistently strive to solidify our leadership position in developing a breadth of products that increases value to our users".

Samples of the APTS003A0X-SRZ and APTS006A0X-SRZ are available now.
