Range of non-isolated DC-DC converters extended

25 January 2006 Power Electronics / Power Management

Bourns has announced the release of an extended range of non-isolated DC-DC converters in industry-standard packaging. The company's non-isolated converters provide the low voltages needed to support core logic, ASICs, microcontrollers and microprocessors. These high-efficiency converters provide improved regulation and superior dynamic response.

Bourns' recently added the X and XT series of low-cost non-isolated DC-DC converters, which use the latest buck topologies and synchronous rectification, to achieve efficiencies up to 95%. Nominal input voltages are 3,3 V, 5 V and 12 V, with output voltages of 0,75 V to 5,5 V dependent on input voltage. Output currents begin at 0 A, and have maximum outputs of 5 A, 6 A, 10 A, and 16 A for any combination of the input and output voltages.

The X and XT series converters offer key features such as an adjustable output voltage (also available as fixed output voltage), remote sense capability, slow start, user on/off, an operating temperature range of -40 to +85°C and sequencing (XT only).

They are available in industry standard RoHS compliant SIP and compact SMD configurations.
