Beta Dyne is protected under various patents, including but not limited to U.S. Patent numbers: 5,777,519; 6,188,276; 6,262,901; 6,452,818; 6,473,3171.
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 synchroniza-
tion and thermal protection. The converter is packaged in a 1 x 2 x .45’’ metal case with six-sided shielding.

1 When converter enters thermal protection on mode, its duty cycle is reduced momentarily and will resume after its internal temperature
(pwm) drops down a few degrees (ºC).The converter’s output behaves similar to hiccup short circuit mode.
2 Contact factory for -55° to +85°C operating temperature range.
3 The maximum input current at any given input range measured at minimum input voltage is given as 1.6*INOMINAL. Nominal input current is the
typical value measured at the input of the converter under full-load room temperature and nominal input voltage ( 24 and 48VIN).
4 Adequate insulation is to be provided to the converters at the end usage as per applicable requirements.
5 Temperature rise on the case of the converters is to be considered during the end usage as per applicable requirements.

Multiple Q25 converters can be synchronized together simply
The SYNC pin can be used to synchronize the internal os- by connecting the converters SYNC pins together as shown in figure
cilllator to external clock. An open drain output is the recommended 8. Care should be taken to ensure the ground potential differences
interface between the external clock to the Q25 SYNC pin as shown between the converters are minimized. In this configuration all the

external clock frequency must be greater than the frequency of the SYNC pin is a CMOS buffer with pull-up current limited to 200micro

amps. If the external device forces the SYNC pin low before the
internal oscillator ramp completes its charging cycle, the ramp will
reset and another cycle begins. If the SYNC pins of multiple Q25
converters are connected together, the first SYNC pin that pulls low
will reset the oscillator ramp of all the other converters. All converters
will operate in phase when synchronized using the SYNC feature.
Up to five devices can be synchronized using this method.
