Bel Power Solutions point-of-load converters are recommended for use with regulated bus converters in an Intermediate Bus Architecture (IBA). The YNV12T10 non- isolated DC-DC converters deliver up to 10 A of output current in an industry-standard through hole (SIP) package. The YNV12T10 converters operate from a 9.6-14 VDC input. These converters are ideal choices for Intermediate Bus Architectures where Point-of-Load power delivery is generally a requirement. They provide a resistor-programmable regulated output voltage of 0.7525 V to 5.5 V. The YNV12T10 converters provide exceptional thermal performance, even in high temperature environments with minimal airflow. This is accomplished through the use of circuit, packaging and processing techniques to achieve ultra-high efficiency, excellent thermal management and a very sleek body profile. The sleek body profile and the preclusion of heat sinks minimize impedance to system airflow, thus enhancing cooling for both upstream and downstream devices. The use of 100% automation for assembly, coupled with advanced power electronics and thermal design, results in a product with extremely high reliability. RoHS lead-free solder and lead-solder-exempted products are available Delivers up to 10 A (50 W) Industry-standard footprint and pinout Intermediate Bus Architectures Single-In-Line (SIP) Package: 2.0 x 0.575 x 0.327 Telecommunications (50.8 x 14.59 x 8.30 mm) Data Communications Weight: 0.25 oz 7 g Distributed Power Architectures Synchronous Buck Converter topology Servers, Workstations Start-up into pre-biased output No minimum load required Operating ambient temperature: -40 C to 85 C High efficiency no heat sink required Remote output sense Reduces Total Solution Board Area Remote ON/OFF (Positive or Negative) Minimizes Part Numbers in Inventory Fixed-frequency operation Auto-reset output overcurrent protection Auto-reset overtemperature protection High reliability, MTBF = 35.5 million hours All materials meet UL94, V-0 flammability rating Approved to the latest edition and amendment of ITE Safety standards, UL/CSA 60950-1 and IEC60950-1 2 YNV12T10 DC-DC Converter Conditions: TA = 25 C, Airflow = 200 LFM (1 m/s), Vin = 12 VDC, Vout = 0.7525 5.0 V, unless otherwise specified.
