POLA DC/DC Power Converters from Murata

The new modules are ideal for supplying POL power to devices such as ASICs, FPGAs and DSPs in a wide range of multi-processor digital systems in applications including datacoms, industrial and medical equipment. A choice of both surface mount and through-hole packages are available; pinouts are identical with the through-hole version giving a slightly lower assembled height.

The MPDTH series achieves a high power conversion efficiency and has an operating temperature range of -40ºC to +85ºC. Output voltage ranges are 0.8V to 2.5V (3.3Vin modules), 0.8V to 3.6V (5Vin modules), and 1.2V to 5.5V (12Vin modules. Output voltages are adjustable and can be set by using a single external resistor.

Key features of the new RoHS compliant POLA modules include auto-tracking, pre-bias immunity start-up support, on/off control, output trim functions. Protection features including input under-voltage lockout, output short-circuit protection and output over-current and over-temperature protections. With the auto-tracking feature, powering FPGA with two different voltage requirements for core and I/O can be met with relatively simple circuit implementation.

Overall dimensions of the MPDTH series are 22.1mm x 12.57mm (6A versions), 25.27mm x 15.75mm (10A versions), and 34.8mm x 15.75mm (15A versions).

POLA, Point of Load Alliance, is a group that promotes multi-sourcing of pin-compatible, non-isolated, point-of-load power modules. It enables power supply designers to choose modules from any member with the assurance that they will provide identical functionality, performance and form factors.
