Non-Isolated DC-DC Converter Family Includes Modules with Outputs Up to 120 A

Non isolated POL convertersBel Power announced the expansion of its VRPx Series of SIP (single inline package) footprint POL (point-of-load) converters to include 30-A, 90-A, 100-A, 110-A and 120-A modules. Operating at efficiencies of up to 95 percent over a wide input range of 4.5 V to 13.8 V, the open-frame series offers a wide output voltage trim range of 0.5 VDC to 5.1 VDC. The fixed frequency devices moreover feature an integrated heat sink to maximize 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 broad array of PC board mounted power applications, the POL modules' SIP package enables their use in almost any space-constrained application in which a 12-V power source is available. The VRPx Series' components switch at a fixed frequency (400 kHz or 500 kHz 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.
