QHS Series – Quarter-Brick DC/DC Converter

48V Input

Data Sheet

12V, 5V, 3.3V, 2.5V, 1.8V, 1.5V, 1.2V Output

When the ON/OFF pin is used to achieve remote

control, the user must take care to insure that the

pin reference for the control is really the -Vin pin.

The control signal must not be referenced ahead

of EMI filtering, or remotely from the unit.

Optically coupling the information and locating the

optical coupler directly at the module will solve

any of these problems.

Typical Application

below shows the recommended

connections for the QHS series converter.

Output Voltage Trim

The QHS series converters do not require any

external components for proper operation.

However, if the distribution of the input voltage to

the converter contains significant inductance, the

capacitor C1 may be required to enhance

performance of the converter. A minimum of a

33μF electrolytic capacitor with the ESR<0.7Ω is

recommended for the QHS series.

Industry Standard Trim

The units trim up with a resistor from the TRIM pin

to the +Sense pin and trim down with a resistor

from the TRIM pin to the –Sense pin as shown in

the Figure 10.

Refer to the “Inrush Current Control Application

Note” on www.power-one.com for suggestions on

how to limit the magnitude of the inrush current.

For output decoupling we recommend to use a

10μF tantalum and a 1μF ceramic capacitors

connected directly across the output pins of the

converter.

Note, that the capacitors do not

substitute the filtering required by the load.

Shutdown Feature Description

The ON/OFF pin in the QHS series converters

functions as a normal soft shutdown.

It is

Figure 10. QHS series positive trim schematic

referenced to the –Vin pin (see Figure 7). With

the positive logic, when the ON/OFF pin is pulled

low, the output is turned off and the unit goes into

a very low input power mode.

The equations below determine the trim resistor

value required to achieve a ΔV change in the

output voltage.

With negative logic, when the ON/OFF pin is

pulled low, the unit is turned on.

∆

An open collector switch is recommended to

control the voltage between the ON/OFF pin and

the -Vin pin of the converter. The ON/OFF pin is

pulled up internally, so no external voltage source

is required. The user should avoid connecting a

resistor between the ON/OFF pin and the +Vin

pin.
