LSN-10A D3 Models www.murata-ps.com Single Output, Non-Isolated, 3.3VIN, 1-2.5VOUT, 10A, DC/DC s in SIP Packages DATELs new LSN D3 Series SIPs (single-in-line packages) are non-isolated DC/DC converters that accept a 3.3V input (3.0V to 3.6V Typical Units input range) and deliver 1V, 1.2V, 1.25V, 1.5V, 1.8V, 2V or 2.5V out- puts at 10 Amps. LSN D3 SIPs are designed to take on-board 3.3V power and convert it, with the highest efficiency in the smallest space, to any lower voltage required by todays current-hungry DSPs, ASICs Features and CPLDs. The miniature size of LSN D3 s makes them ideal for true point-of-use power Industry-standard SIP pinout processing. Vertical-mount packages occupy a mere 0.7 square inches (440 sq. Shorter (2.0 vs. 2.5 ) package length mm), and they are available in industry-standard and Tyco-compatible pinout. Horizontal-mount packages suffix) are only 0.34 inches (8.6mm) high. 3.0-3.6V input range The LSN s best-in-class power density is achieved with a fully synchronous, 1/1.2/1.25/1.5/1.8/2/2.5V outputs 10A fixed-frequency (300kHz), buck topology that also delivers: high efficiency (94% for Non-isolated, fully synchronous, 2.5VOUT models), low noise (10mVp-p typ.), tight line/load regulation (0.1%/0.25% 300kHz, buck topology max.), quick step response (100sec), stable no-load operation, and no output Outstanding performance: reverse conduction. The fully functional LSNs feature output overcurrent detection, continuous short- 1% setpoint accuracy circuit protection, an output-voltage trim function, a remote on/off control pin Efficiencies to 94% 10 Amps (pull high to disable), thermal shutdown, and a sense pin. High efcfi iency enables the Noise as low as 10mVp-p LSN D3 s to deliver rated output currents of 10 Amps at ambient temperatures to Stable no-load operation +71C with no air flow (natural convection). Trimmable output voltage If your low-voltage, high-current requirements have made the use of inefficient Remote on/off and sense pins linear regulators impractical, take a look at one of DATELs easy-to-use, low-cost LSN SIPs. All devices are UL/IEC/EN60950 certified and EMC compliant. UL, CB, Thermal Shutdown HALT and EMC reports are available upon request.
