DC-DC Converter

The NiQor quarter-brick dc-dc converter is a non-isolated

buck-boost regulator, which employs synchronous

rectification to achieve extremely high conversion efficiency.

The High Input Voltage NiQor Brick family of converters can

be used in traditional DPA (distributed power architecture)

systems or provide a regulated output voltage from a

battery source or other variable voltage source. The NiQor

Brick family can be configured to Buck the input voltage

down to a lower voltage or Boost the input voltage up to

a higher voltage using a single external resistor. These

modules are RoHS 6/6 compliant (see last page).

BASIC OPERATION AND FEATURES

These converters use a digital controller for the buck stage and

boost stage (see Figure A). It automatically changes operating

mode (buck mode or boost) when the line voltage or output set

point changes. Both stages are accomplished with synchronous

rectifiers. Very high efficiency is maintained over wide input

and output ranges by shifting operational modes and use of

synchronous rectifiers.

JUMPER

To maintain the accuracy of the output voltage over load current,

it is vital that any trim-up resistor be terminated directly to the

converter’s Sense(-) pin (S option) or Vout(-) pin (C option), not

at the connection to the load. A separate Kelvin connection to the

PCB pad for the Vout(-) is optimal.

PROTECTION FEATURES

W mode: Q3, Q4 are populated, Jumper is open.

T mode: Q3, Q4 are open, Jumper is populated.

Input Under-Voltage Lockout: The converter is designed

to turn off when the input voltage is too low, helping avoid an

input system instability problem, described in more detail in the

application note titled “Input System Instability”. The lockout

circuitry is a comparator with DC hysteresis. When the input

voltage is rising, it must exceed the typical Turn-On Voltage

Threshold value (listed on the specification page) before the

converter will turn on. Once the converter is on, the input

voltage must fall below the typical Turn-Off Voltage Threshold

value before the converter will turn off.

The converter runs at a fixed frequency with a predictable

EMI performance.

This series of quarter-brick and eighth-brick converters use the

industry standard footprint and pin-out configuration.

CONTROL FEATURES

REMOTE ON/OFF: The ON/OFF input permits the user to con-

trol when the converter is on or off. Only Negative ON/OFF logic

is available in this power module series.

Output Current Shutdown: To provide protection in an

output short condition, the unit is equipped with internal short

circuit protection. When the short protection is triggered, the

unit shutdowns first. After approximately 16 ms inhibit time, the

units turn on again. If the short condition remains, the current

limit circuit will limit the output current. The units operate

normally once the fault condition is removed.

Negative logic ON/OFF signal turns the module OFF during logic

high (leave the pin floating or set voltage between 1.8~3.3 V) and

turns the module ON during logic low [tie to V_in(-)].

Internal Over-Voltage Protection: To fully protect from

excessive output voltage, the output over-voltage shutdown

circuitry is contained. This OVP is independent of the trimmed set

point. The shutdown point is fixed on the standard option.

OUTPUT VOLTAGE TRIM: The output voltage can be

programmed to any voltage between 0 V dc and V_maxby

connecting one resistor between the Pin 6 (TRIM) pin and Pin 5

[Sense(-)]. For a desired output voltage, the value of the resistor

should be:

Over-Temperature Shutdown: A temperature sensor on

the converter senses the average temperature of the module.

The thermal shutdown circuit is designed to turn the converter

off when the temperature at the sensed location reaches the

Over-Temperature Shutdown value. It will allow the converter

to turn on again when the temperature of the sensed location

falls by the amount of the Over-Temperature Shutdown Restart

Hysteresis value.

APPLICATION CONSIDERATIONS

Vin-/

Vout+

Vin+

Cin2

Limited output voltage resolution: The internal voltage

control feedback loop has limited resolution. Therefore, the

output voltage will exhibit discrete steps as the loop responds

to changes in line, load, trim, or remote sense. For instance,

on close examination, the startup ramp has a “stair-step”

shape. Likewise, a load transient response will be composed

of multiple discrete steps.

Input filtering: These modules should be connected to a

low-impedance source. A highly inductive source can affect the

stability of the module. An input capacitance must be placed

directly adjacent to the input pin of the module, to minimize

input ripple voltage and ensure module stability.

Figure B: Negative output setup

Using this negative output setup impacts the available output

voltage range and current limit.

The output voltage range becomes 0 to V_max- V_in, and the cur-

Output capacitance: For stable operation of the module, there

is no extra external capacitor required. To reduce the output

ripple and improve dynamic response to a step load change,

additional capacitance at the output can be used. Low ESR

polymer and ceramic capacitors are recommended to improve

the dynamic response of the module. In many applications,

however, additional external output capacitance is a requirement

which will cause the startup time to change.

rent limit is scaled by:

V_in

(V_in+ V_out)

Current monitor/trimmable current limit (C option): In

addition to voltage trim, the C option offers an adjustable current

limit input and a current monitor output. The C option also

includes an ideal diode circuit in series with the Vout+ pin that

prevents reverse current flow. This enables applications such as

battery charging, current sharing, and current read back.

Remote sense (S option): Vout remote sensing is provided

to achieve proper regulation at the load points and reduce

effects of distribution losses on output line. In the event of an

open remote sense line, the module shall maintain local sense

regulation through an internal resistor. The module shall correct

for a total of 10% Vout.
