Functional Description The Q25 series is a 25-30W low noise isolated converter, consisting of 14 standard single & dual output models from 3.3VDC to 15 VDC and 4:1 input voltage range from 9V to 72V. Output synchronous rectification followed by a very low dropout linear regulator made possible to achieve up to 87% efficiency and less than 5mV output noise with external capacitors. Standard features include input undervoltage protection , external synchronization and thermal protection. The converter is packaged in a 1 x 2 x .45’’ metal case with six-sided shielding. +Vin 4 6 LINEAR REG 1 PWM & SWITCHING TRANSISTOR GND 3 SYNCHRONOUS RECTIFIERS & FILTER 7 8 9 +S +Vout -Vout -S ON/OFF SYNC IN 2 -Vin ERROR OP-AM 5 V ADJ VREF Typical Block Diagram BETA DYNE INC • WWW.BETA-DYNE.COM Q25 DC/DC CONVERTER • Q25_DS_RevA.PDF • PAGE 1 OF 9 www.DataSheet.in Unless otherwise specified, all parameters are given under typical ambient temperature of +25°C with an airflow rate = 400LFM.
