What Are They?
DATEL's new LSN D5 Series SIP's are non-isolated DC/DC converters that accept 5V inputs (4.5V-to-5.5V input range) and deliver 1/1.2/1.5/1.8/2/2.5/3.3V outputs fully rated at 10 Amps. The LSN's single-in-line (SIP) packages (2" x 0.5" x 0.34", 51 x 13 x 8.6mm) can be configured in either vertical or horizontal orientations. The former occupies a mere 0.7 square inches. The latter is a mere 0.34 inches (8.6mm) high.
LSN D5's are true "plug-and-play" power converters enabling power-system architects to literally configure solutions in minutes. In most applications, LSN's require no external I/O filtering to achieve either specified noise levels or FCC-compliant radiated/conducted emissions. They are designed with on-board input/output caps fully rated to handle the required input ripple current and fully capable of reducing output noise to specified levels.
And They're Very Affordable
Not needing transformers, optocouplers nor complicated FET drive circuits in their secondary, non-isolated DC/DC's are considerably cheaper than their isolated brethren. LSN D5 Series SIP DC/DC's are attractively priced at $19.90 (USA) each in singles and $11 .90 each for 10k pieces. Higher quantities are priced as low as $9.95 each . . . a buck an Amp!
Save Money in Legacy 5V Systems
If you're upgrading the performance of traditional 5V systems (such as blade-server or mass-storage cards) and require lower voltages (1-3.3V) for new processors, PLD's or ASIC's, the LSN D5 SIP's enable you to efficiently and cost-effectively develop any voltage you need right where you need it.
Save Money in New 5V Systems
If you're contemplating an "intermediate-bus" architecture as a means of saving money in new moderate-power, multi-voltage applications, analysis shows that 5V on-board buses (which cost no more than 12V intermediate buses) can achieve higher overall system efficiencies. This is due to the outstanding efficiencies achievable by 5V-input non-isolated DC/DC's, like the LSN D5's.
The D5 LSN's best-in-class power density is achieved with a fully synchronous, fixed-frequency (300kHz), buck topology that delivers: high efficiency (96% for 3.3VOUT models @ 50% load), low noise (l0mVp-p typ., 35mVp-p max.), tight line/load regulation (±0.1%/±0.25% max.), quick step response (50µsec), stable no-load operation (for load circuits going into "sleep" mode), and no output reverse conduction.
High efficiency enables LSN SIP's to deliver more output current at temperature than all competing devices. All LSN D5's deliver full power to at least +65°C with no supplemental air flow. With minimal air (100lfm), all models operate at full power to at least +75°C.
The LSN feature set includes output overcurrent detection, continuous short-circuit protection, thermal shutdown (+115°C), ±10% output-voltage trim, remote on/off control, output sense pins, optional vertical or horizontal package orientation, and optional "reverse" pinning (for Tyco compatibility) on vertical models.
Free LSN D5 sample/evaluation units for qualified OEM's, and/or pre-production quantities up to 25 pieces, are immediately available from stock. Production quantities require 6-8 weeks.
