The Q24T25015 DC-DC Converter is a state-of-the-art power solution designed for a wide range of applications, including telecommunications, data communications, wireless technologies, and server infrastructures. Compatible with 18-36 VDC input and delivering 1.5 VDC at a substantial 25A output, this converter sets a precedence with an ultra-high efficiency level and superior thermal performance in a quarter-brick form factor.
Features
The Q24T25015 offers an array of features valuable to electronic engineers and designers. It can deliver up to 25A, showcasing higher current capabilities even at elevated temperatures (70°C) when compared to other converters in its class. An impressive efficiency of 83.5%, regardless of being at full or half load (25 A or 12.5 A), makes it an energy-efficient choice.
Noteworthy is its low-profile design, measuring just 0.28 inches in height and weighing approximately 28 grams, allowing for easy integration without heat sinks. The converter provides a fixed-frequency operation, remote output sense, and output voltage trim ranging from +10% to -20%. Furthermore, the converter is fully protected, including over-voltage, over-temperature with auto-restart feature, and under an impressive 2.6 million hours MTBF (Mean Time Between Failures).
Boasting compatibility with RoHS directives, the Q24T25015 is versatile, offering lead-free solder or lead-solder-exempted versions. With its industry-standard footprint and pinout, the converter meets the Basic Insulation Requirements of EN60950 and includes an onboard LC input filter. The model has approvals from UL 60950 in the U.S. and Canada, and DEMKO certified per IEC/EN 60950.
Electrical Specifications
The converter upholds robust electrical specifications with a wide operating input voltage range from 18 to 36 VDC and features non-latching under-voltage lockout. It can handle an external load capacitance of up to 30,000 MF and an output current range of 25 ADC with non-latching current limit inception and protection mechanisms. It also includes ISO 2000 VDC isolation and offers features such as switching frequency at 435 kHz, output over-voltage protection, and over-temperature shutdown.
With its remote sense compensation and ON/OFF control available in both positive and negative logic, the converter ensures precise power delivery and flexible integration options. The note regarding the output voltage suggests that while it can be increased up to 10% through various means, the total trim should not surpass 10% to maintain the effectiveness of over-voltage protection.
Performing Under Varying Conditions
The datasheet includes a detailed figure (Fig: 1) demonstrating the available load current in relation to ambient air temperature and airflow rates, emphasizing the converter’s reliability even under fluctuating thermal conditions.
The Q24T25015 DC-DC Converter combines advanced circuitry, high-quality assembly, and superior packaging to offer unsurpassed quality and reliability in demanding power applications, with certifications to match.
