SQE48T10120-NDA0G Preview

The new high performance 10A SQE48T10120 DC-DC converter provides a

high efficiency single output, in a 1/8th brick package that is only 62% the size

of the industry-standard quarter-brick. Specifically designed for operation in

systems that have limited airflow and increased ambient temperatures, the

SQE48T10120 converter utilize the same pinout and functionality of the

industry-standard quarter-bricks.

The SQE48T10120 converter thermal performance is accomplished through

the use of patented/patent-pending circuits, packaging, and processing

techniques to achieve ultra-high efficiency, excellent thermal management,

and a low-body profile.

Low-body profile and the preclusion of heat sinks minimize impedance to

system airflow, thus enhancing cooling for both upstream and downstream

devices. The use of 100% automation for assembly, coupled with advanced

electronic circuits and thermal design, results in a product with extremely high

reliability.

Operating from a 36-75V input, the SQE48T10120 converter provides a 12V

output voltage that can be trimmed from –20% to +10% of the nominal output

voltage, thus providing outstanding design flexibility.

With standard pinout and trim equations, the SQE48T10120 converter is a

perfect drop-in replacement for existing 10A quarter-brick designs. Inclusion

of this converter in a new design can result in significant board space and cost

savings. The designer can expect reliability improvement over other available

converters because of the SQE48T10120’s optimized thermal efficiency.

These power converters have been designed to be stable with no external capacitors when used in low inductance input

and output circuits.

However, in some applications, the inductance associated with the distribution from the power source to the input of the

converter can affect the stability of the converter. A 33 µF electrolytic capacitor with an ESR < 1

Ω

across the input is

recommended to ensure stability of the converter.

In many applications, the user has to use decoupling capacitance at the load. The power converter will exhibit stable

operation with external load capacitance up to 5000 µF.

The ON/OFF pin is used to turn the power converter on or off remotely via a system signal. There are two remote control

options available, positive and negative logic, with both referenced to Vin(-). A typical connection is shown in Figure A.

Figure A. Circuit configuration for ON/OFF function.

The positive logic version turns on when the ON/OFF pin is at a logic high and turns off when at a logic low. The converter

is on when the ON/OFF pin is left open. See the Electrical Specifications for logic high/low definitions.

The negative logic version turns on when the pin is at a logic low and turns off when the pin is at a 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.

The ON/OFF pin is internally pulled up to 5V through a resistor. A properly de-bounced 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 0.2 mA at

a low level voltage of



0.8 V. An external voltage source (±20 V maximum) may be connected directly to the ON/OFF input,

in which case it must be capable of sourcing or sinking up to 1 mA depending on the signal polarity.

See the Startup Information section for system timing waveforms associated with use of the ON/OFF pin.

The remote sense feature of the converter compensates for voltage drops occurring between the output pins of the converter

and the load. The SENSE(-) (Pin 5) and SENSE(+) (Pin 7) pins should be connected at the load or at the point where regulation

is required (see Figure B).

Figure B. Remote sense circuit configuration.

tech.support@psbel.com

CAUTION

If remote sensing is not utilized, the SENSE(-) pin must be connected to the Vout(-) pin (Pin 4), and the SENSE(+) pin must

be connected to the Vout(+) pin (Pin 8) to ensure the converter will regulate at the specified output voltage. If these

connections are not made, the converter will deliver an output voltage that is higher than the specified data sheet value.

Because the sense leads carry minimal current, large traces on the end-user board are not required. However, sense traces

should be run side by side and located close to a ground plane to minimize system noise and ensure optimum performance.

The converter’s output overvoltage protection (OVP) senses the voltage across Vout(+) and Vout(-), and not across the sense

lines, so the resistance (and resulting voltage drop) between the output pins of the converter and the load should be

minimized to prevent unwanted triggering of the OVP.

When utilizing the remote sense feature, care must be taken not to exceed the maximum allowable output power capability

of the converter, which is equal to the product of the nominal output voltage and the allowable output current for the given

conditions.

When using remote sense, the output voltage at the converter can be increased by as much as 10% above the nominal

rating in order to maintain the required voltage across the load. Therefore, the designer must, if necessary, decrease the

maximum current (originally obtained from the derating curves) by the same percentage to ensure the converter’s actual

output power remains at or below the maximum allowable output power.

The output voltage can be adjusted up 10% or down 20%, relative to the rated output voltage by the addition of an externally

connected resistor. Trim up to 10% at full load is guaranteed at Vin

≥

40V

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 SENSE(-) pins.

To increase the output voltage, refer to Figure C. A trim resistor, R

T-INCR

, should be connected between the TRIM (Pin 6) and

SENSE(+) (Pin 7), with a value of:
