Description
The new Q2D series of dual output DC/DC converters offer unprecedented density and performance in an
industry standard, quarter-brick footprint. Patent pending technology and state-of-the-art packaging
techniques achieve a total of 30A (25A for 5V output) output current, 15A (10A for 5V output) per channel,
without a heatsink. Extremely low profile (<8mm or 0.30”) enables the converters to be used in applications
where spacing between circuit boards is limited. The 100% surface-mount design provides consistent high
quality and reliability. The SMT mounting option eliminates the need for separate (additional manual)
process in attaching the converters to the motherboards during mass production.

0.2 mA at a low level voltage of ≤ 0.8 V, and
sourcing up to 0.5 mA at high logic level of 5 V;
higher current capability is required for control
voltages greater than 5 V. See the Start-up
Information section for system timing waveforms
associated with use of the ON/OFF pin.
Application
Input and Output Impedance
These power converters have been designed to
be stable with no external capacitors when used
in low inductance input and output circuits.
Output Voltage Adjust /TRIM (Pin 6)
However, in many applications, the inductance
associated with the distribution from the power
source to the input of the converter can affect the
stability of the converter. The addition of a 33 µF
electrolytic capacitor with an ESR < 1 Ω across
the input helps ensure stability of the converter. In
many applications, the user has to use decoupling
capacitance at the load. The converter will exhibit
stable operation with external load capacitance up
to 10,000 µF on 3.3 V and 4,700uF on 5 V output.
The converter’s output voltages can be adjusted
simultaneously up 10% or down 10% relative to
the rated output voltages by the addition of an
externally connected resistor.
The TRIM pin should be left open if trimming is
not being used. To minimize noise pickup, a 0.1
µF capacitor is connected internally between the
TRIM and RETURN pins.

The ON/OFF pin is used to turn the power

The positive logic version turns on when the

logic low. The converter is on when the ON/OFF
pin is left open.

Vout1 (+)
The negative logic version turns on when the pin
is at logic low and turns off when the pin is at logic
high. The ON/OFF pin can be hard wired directly
to Vin(-) to enable automatic power up of the
converter without the need of an external control
signal.
Fig. 13: Configuration for Decreasing Output Voltage.
To decrease the output voltage, a trim resistor RT-
DECR, (Fig. 13) should be connected between the
TRIM (Pin 6) and Vout1(+) pin (Pin 4), with a
value from the table below, where:
A mechanical switch, open collector transistor, or
FET can be used to drive the input of the ON/OFF
pin. The device must be capable of sinking up to

Output Over-Current Protection (OCP)
Δ [%]
Δ [%]
The converter is protected against over-current or
short circuit conditions on both outputs. Upon
sensing an over-current condition, the converter
will switch to constant current operation and
thereby begin to reduce output voltages. If, due
to current limit, the output voltage Vout1 (3.3 V)
drops, than Vout2 (5.0 V) will follow Vout1 with
less than 1 V difference. Drop on Vout2 output
due to current limit will not affect voltage on
Vout1. For further load increase, if either Vout1
drops below 1 Vdc or Vout2 drops below 2 Vdc,
the converter will shut down.

Once the converter has shut down, it will attempt
to restart nominally every 100 ms with a 2% duty
cycle. The attempted restart will continue
indefinitely until the overload or short circuit

The converter will shut down if the output voltage

and RETURN (Pin 5) exceeds the threshold of the
OVP circuitry. The OVP protection is separate for
Vout1 and Vout2 with their own reference
independent of the output voltage regulation
loops. Once the converter has shut down, it will
attempt to restart every 100 ms until the OVP
condition is removed.

Note 2: The above trim resistor values match

Over-Temperature Protection (OTP)
The converter will shut down under an over-
temperature condition to protect itself from
overheating caused by operation outside the
thermal derating curves, or operation in abnormal
conditions such as system fan failure.
Input Under-Voltage Lockout
The over-temperature protection circuit turns the
converter off when the temperature at a sensed
location reaches 120°C (typical). Once the
converter has shut down, it will restart when the
temperature at the sensed location falls below
110°C.
Input under-voltage lockout is standard with this
converter. The converter will shut down when the
input voltage drops below a pre-determined
voltage.
The input voltage must be at least 35 V for the
converter to turn on. Once the converter has been
turned on, it will shut off when the input voltage
drops below 31 V. This feature is beneficial in

The Q2D series converters are designed for
natural or forced convection cooling.
The
maximum available output power of the
converters is determined by the maximum
semiconductor junction temperature. To provide
reliable long-term operation of the converters,
Power-One limits maximum allowable junction
temperature to 120°C.

The graphs in Figures 14-20 show the maximum
output current of the Q2D series converters at
different local ambient temperatures at both
natural and forced (longitudinal airflow direction,
from pin 3 to pin 4) convection.
