High performance 60-A DC-DC converter features four programmable outputs

November 03, 2011 // Paul Buckley

Semiconductor Circuits, Inc., has introduced the FLEX-4 'Cool Power Technologies' 7-15 Vin (4.75 – 5.5 Vin versions available), 60 A max. non-isolated DC-DC converter with four fully programmable outputs. Each of the four outputs can be programmed from 0.6 V to 5.1 Vout (up to 80% of Vin if required.)

The high efficiency module allows for up to 60 A of combined output current – 2 to 20 A outputs and 2 to 10 A outputs. An additional 5th output (LDO) is programmable to 5 V or 3.3 V and up to 50 mA output current. Output startup/shutdown delay and ramp time allows for fully programmable output sequencing. 2 GPIOs (up to 4 if needed) can be programmed to indicate power good or fault conditions or be used as I/O to enable other output(s) as required. OTP, OVP, UVLO and Current Limit levels are all fully programmable to customer requirements.     

These units are ideally suited for space constrained applications requiring up to five voltage rails. Set top boxes, servers, storage, ATE, video processing, game systems, networking and telecommunications equipment are among the many possible applications for this product. The Flex-4 is a high efficiency module with efficiencies exceeding 90% from ½ load through full load. The module complies with all of the typical industry requirements including no load operation; and startup into a pre-biased load at startup.     

The pick & place capable surface-mount module is 2.60 inch L x 0.8 inch W (66.04 mm x 20.321 mm.) The device has a maximum mounted height of 0.365 inch (9.28 mm) which accommodates tight card spacing with minimal airflow blockage of downstream components.
