VRPx SeriesBel Power announced the expansion of their VRPx Series of SIP (single inline package) footprint POL (point-of-load) converters to include 30A, 90A, 100A, 110A and 120A modules. These non-isolated DC/DC converters are the latest addition to Bel Power’s portfolio of SIP converters that now comprise vertical and horizontal mount parts capable of delivering 3A to 120A of output current. Operating at efficiencies of up to 95% over a wide input range of 4.5V to 13.8V, the cost-effective, open-frame series offer an ultra-wide output voltage trim range of 0.5 Vdc to 5.1 Vdc. The fixed frequency devices moreover feature an integrated heatsink to maximize usable power density. Notably included in the series are step-down DC/DC converters boasting 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 12V power source is available. The VRPx Series' competitive pricing and compact size make Bel Power's newest DC/DC converters ideally suitable for employment in such networking and telecommunications equipment as servers, workstations, computers and peripherals.

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

In production quantities, per-piece pricing for the VRPx Series of non-isolated DC/DC converters is $9.35 and $17.20, for the 30A and 90A modules, respectively. Parts featuring outputs of 100A, 110A and 120A are priced at $18.35 each. Samples and production quantities are available from stock with lead times of up to 12 weeks.
