DATEL Announces New LEN Series Converters

Datel Inc. (Mansfield, MA) presented its new LEN Series of high-current, point-of-load (POL), non-isolated, dc/dc converters, which accept a 12V ±15% input and convert it to any lower voltage from 0.8V to 3.3V at 28A, or 5V at 25A. The LEN Series uses a two-phase, fixed-frequency (320kHz), buck-regulator design that enables simultaneous delivery of high-efficiency (85% for 0.8VOUT to 96% for 5VOUT), low-noise (20mVp-p to 30mVp-p), quick-step response (100µsec), and a wide operating temperature range (to +70°C without derating).

The LEN Series uses the well-established eighth-brick (E-brick) form factor (2.3in x 0.9in x 0.46in) and the newly established, non-isolated, eighth-brick pinout. The soon-to-be-multi-sourced pinout doubles (from two to four) the number of output and return pins. This inter-digitated approach effectively halves losses due to pin resistance and inductance, and facilitates output filtering. The new E-brick package is offered in both standard through-hole and new surface-mount versions.

In small quantities, the LEN Series is priced at $45 each. In OEM quantities of 10,000 pieces, the LEN Series is priced at $29 each. Free sample/evaluation units for qualified OEMs and/or pre-production quantities (<25 pieces) are immediately available from stock. Production quantities require six to eight weeks.
