SIP POL converters suited for telecommunications

Now including the 30A, 90A, 100A, 110A and 120A modules, the series of non-isolated DC/DC converters comprise vertical and horizontal mount parts capable of delivering 3 to 120A of output current.

Operating at efficiencies of up to 95 per cent over an input range of 4.5 to 13.8V, the cost-effective, open-frame series offer an output-voltage trim range of 0.5 to 5.1V DC.

The fixed-frequency devices feature an integrated heatsink to maximise usable power density.

Included in the series are step-down DC/DC converters offering an IMON pin for output current monitoring and parts with a Power State Indicator (PSI) pin for phase dropping and higher efficiency during light-load states.

Step-down DC/DC converters, compatible with Intel VRM11.1 requirements, are also provided.

Components are designed to meet worldwide standards for safety and performance, and are RoHS EU Directive 2002/95/EC-compliant.

Engineered for a range of PC-board-mounted power applications, the POL modules' SIP package enables their use in almost any space-constrained application in which a 12V power source is available.

Featuring a remote on/off pin, low ripple current and differential remote sense, the VRPx Series' components switch at a fixed frequency (400 or 500KHz module dependent).

They incorporate control and protection features including input under-voltage lockout, output over current/short circuit protection, 2-, 3-, or 8-bit VID (Voltage Identification Digital) and a power-good signal.
