Surface mount switching regulators for Point of Load designs
The SVR series of non-isolated switching regulators from XP Power is aimed at point of load (PoL) designs

XP Power has launched a family of surface mount and VR through-hole, non-isolated DC-DC switching regulators.

The SVR series has efficiencies of up to 96 percent and operating temperatures of -40°C to +85°C to replace linear regulators in Point of Load (PoL) distributed power designs. The devivces operate from a wide input range of up to 36V and feature a low quiescent current, making them suitable for a variety of applications & battery powered electronic equipment.

There are two variants in the SVR range, each offering different maximum output currents. The SVR05 series of 0.5A devices offer output voltage models between 1.5V and 15V, and a low standby current of less than 100µA with remote on/off. The SVR10 series of 1.0A switching regulators has output voltage models from 1.5V to 12V and standby current of less than 1mA with remote on/off. Both devices are housed in a compact SMD package measuring 15.24 x 8.5 x 8.25mm (L x W x H) and offer efficiency levels of up to 95 percent.

The VR range of SIP3 packaged switching regulators is offered in three variants; the VR05 (0.5A) consumes as little as 0.2mA when idle and the VR10 (1.0A) consumes as little as 0.3mA. Both series offer regulated single outputs from 3.3 to 15V. The VR20 (2.0A) covers outputs from 2.5V to 15V, and each model consumes 0.1mA when idle.

Both the SVR and VR families comply with EN55032 Class B conducted and radiated emissions with external components and meet EN61000-4-2, -3, -4, -5, -6 immunity standards. Common features include continuous short circuit protection with auto-recovery and overload protection. Typical applications include portable and battery-operated equipment, sensors, robotics, instrumentation, telecommunications, embedded computing, medical devices and distributed DC supply systems requiring regulation but not needing isolation. All models have MTBF figures over 2Mhrs and come with a 3-year warranty.

The SVR and VR switching regulators are available now from Digi-Key, Farnell, Mouser, RS Components, approved regional distributors, or direct
