Converters suit elevated-temperature environments
FDK
DC/DC converters
FDK has extended its DK series with three non-isolated, point-of-load (PoL) DC/DC converters that operate from a 3.0VDC to 5.5VDC input bus for telecommunications and computing applications.
The small, low-profile surface-mount devices deliver up to 3, 4 and 6A of output current with efficiencies up to 94 per cent, the company said.
They provide a tightly regulated programmable output voltage in the range of 0.8VDC to 3.465VDC and deliver the full rated output current with no derating in ambient temperatures up to 85C under natural convection.
The 3A model FPDK05SR8003PSV, 4A model FPDK05SR8004PSV, and 6A model FPDK05SR8006PSV are offered in a 0.657 x 0.402in (16.7 x 10.2mm) SMD package.
The products occupy a footprint of less than 0.3in2 (2cm2).
Their low height of 0.134in (3.4mm) for the 3A and 4A converters and 0.173in (4.4mm) for the 6A converter makes them particularly suitable for high-density racks, blade systems, and low-profile consumer applications with limited board-to-board and board-to-case clearances.
The DK series converters provide complete power conversion solutions without the need for external input and output capacitors.
They are true single-input converters in that they do not require an external VCC (bias) supply for operation.
They feature programmable output voltage, remote on/off, over-current and over-temperature protection, a 'power good' signal, and start up into a pre-biased output.
They fit a wide range of telecommunications, data communications, computing, industrial, and consumer applications where board space, cost, profile, efficiency, and reliable operation in elevated temperature environments are critical.
All DK series products are RoHS compliant.
