1 / 19 page Technical Reference Notes ALQ15XX48X Series (Open Frame Dual Output Quarter Brick) MODEL: ALQ15 SERIES SHEET 1 OF 19 MARCH 4, 2004 - REVISION 01 ALQ15 Dual Output Open-Frame DC-DC Converter Module Industry Standard ¼ Brick: 36V-75V Input / 60W Output Power The ALQ15 series is Astec's latest dual output; high-density converter offering that comes in an industry standard ¼ brick open-frame package. With its independently controlled output rails, the module effectively minimizes cross regulation, which has been an issue to most dual converters available in the market. The ALQ15 series has been designed to deliver 60W of clean, well-regulated, low noise DC power for today's demanding loads at respectable efficiency levels: 3.3V-2.5V combination @ 87.5% (60W output power). Output combinations currently available are 5.0V/3.3V - 3.3V/2.5V - 3.3V/1.8V - 2.5V/1.5V, with each output rail able to deliver 15A max (5V@12A). The module comes with standard feature sets such as output enable with positive or negative options; output voltage-adjust; over current, over voltage and over temperature protection. In addition, it is also being offered at both 5mm (std) and 3.7mm pin lengths. Special Features • Tight Regulation • Low Ripple and Noise at < 30mVPK-PK • Industry Standard ¼ Brick Footprint • Positive and Negative Enable Options • Regulation to Zero Load • High Capacitive Load Start-up • Fixed Switching Frequency • Output Trim • Input Under-Voltage Lockout • Basic Insulation Environmental Specifications • -40ºC to 85ºC Operating Temperature • -55ºC to 125ºC Storage Temperature • Designed for > 1 million hours MTBF Electrical Parameters Input Input Range 36-75 VDC Input Surge 100V / 100ms Efficiency 5.0V/3.3V @ 89.5% (Typ at 60W) 3.3V/2.5V @ 87.7% 3.3V/1.8V @ 86.5% 2.5V/1.5V @ 84.0% Control Enable TTL compatible (Positive and Negative Enable Options) Output Load Current 15A max per channel (60W max) 5V @ 12A max Line/Load Regulation < 1% VO (Typ) Ripple and Noise 30mVPK-PK Output Voltage Adjust Range ±10% Vo Transient Response 3% VO deviation max (3.3V) 50% to 75% Load Change 220 µsec typical settling time (for 3.3V) Over Current Protection 130% IO,max typical Safety UL + cUL 60950, Recognized EN60950 through TUV-PS CB Report |
