FDK Intros Low Input Mini POL Converters
Low-voltage SIP DC-DC converters.
San Jose, CA and Tokyo, Japan — FDK Corporation has extended its DK Series of non-isolated, point-of-load (POL) DC-DC converters with the addition of three new converters that operate from a 3.0VDC to 5.5VDC input bus.

These very small, low profile single-in-line package (SIP) devices deliver up to 3, 4, and 6 Amp of output current with efficiencies up to 94 percent. They provide a tightly regulated programmable output voltage in the range of 0.8 to 3.465VDC. The 3A and 4A models deliver the full rated output current with no derating in ambient temperatures up to 85 and 75°C respectively with natural convection. The 6A converter delivers the full rated output current with no derating up to 60°C with 400LFM (2m/s) airflow.

The 3A model FPDK05TR8003PSV and the 4A model FPDK05TR8004PSV are offered in a 0.394 x 0.185-in. (10.0 x 4.7mm) SIP package. The 6A model FPDK05TR8006PSV is offered in a 0.394 x 0.220-in. (10.0 x 5.6mm) SIP package. Occupying a footprint of less than 0.08-in.2 (0.5cm2) for the 3A and 4A models, and 0.09-in.2 (0.6cm2) for the 6A model, they provide significant space savings over discrete on-board solutions. All models have a low height of 0.472-in. (12.0mm), making 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 power conversion solutions without the need for external input and output capacitors.

The units are true single-input converters and do not require an external Vcc (bias) supply for operation. They provide programmable output voltage, remote ON/OFF, over-current and over-temperature protection, 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.
