The new SSQE48T15033 DC-DC converter is an open frame

sixteenth-brick DC-DC converter that conforms to the Distributed

Open Standards Architecture (DOSA) specifications. The converter

operates over an input voltage range of 36 to 75 VDC, and provides a

tightly regulated output voltage with an output current up to 15 A. The

output is fully isolated from the input and the converter meets Basic

Insulation requirements permitting a positive or negative output

configuration.

The converter is constructed using a single-board approach with both

planar and discrete magnetics. The standard feature set includes

remote On/Off (positive or negative logic), input undervoltage lockout,

output overvoltage, overcurrent, and short circuit protections, output

voltage trim, and overtemperature shutdown with hysteresis.

With standard pinout and trim equations and excellent thermal

performance, the SSQE48T15033 converters can replace in most

cases existing eighth-brick converters. Inclusion of this converter in a

new design can result in significant board space and cost savings.

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 < 1Ω across the input is

recommended to ensure stability of the converter over the wide range of input source impedance.

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 20,000 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, both referenced to Vin(-). A typical connection is shown in Fig. 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 the pin is 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 5 V 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 Fig. B).
