YV12T25 DC-DC Converter 10 - 14 VDC Input 0.8 - 5.5 VDC Programmable 25 A Data Sheet The Products: Y-Series Features RoHS lead-free solder and lead-solder-exempted products are available Delivers up to 25 A Input range 10 - 14 V Small size and low profile: 1.25 x 2.00 x 0.335 (31.7 x 50.8 x 8.50 mm) Applications Start-up into pre-biased output Intermediate Bus Architectures No minimum load required Telecommunications Operating ambient temperature: -40 C to 85 C Data communications Remote output sense Distributed Power Architectures Remote ON/OFF Servers, workstations Fixed frequency operation (500 kHz) Auto-reset output overcurrent protection High reliability, MTBF = 23 Million Hours Benefits All materials meet UL94, V-0 flammability rating High efficiency no heat sink required UL60950 recognition in U.S. & Canada, and Cost effective certification per IEC/EN60950 Reduces Total Solution Board Area Description Power-Ones point-of-load converters are recommended for use with regulated bus converters in an Intermediate Bus Architecture (IBA). The YV-Series of non-isolated dc-dc converters deliver up to 25 Amps of output current in a through-hole (SIP) package. Operating from a 10 - 14 VDC input, the YV12T25 converter is an ideal choice for Intermediate Bus Architectures where Point-of-Load (POL) power delivery is a requirement. The converter provides an extremely tight regulated programmable output voltage of 0.80 V to 5.5 V. The YV-Series of converters provide exceptional thermal performance, even in high temperature environments with minimal airflow. This performance is accomplished through the use of advanced circuitry, packaging and processing techniques to achieve a design possessing ultra-high efficiency, excellent thermal management, and a very low body profile. The low body profile minimizes impedance to system airflow, thus enhancing cooling for both upstream and downstream devices. The use of automation for assembly, coupled with advanced power electronics and thermal design, results in a product with extremely high reliability.
