APC12 Centauri II
Centauri II (APC12) Non-Isolated DC/DC Power Module
Tiny SMT Footprint – 1.8V-12V Input, 0.9V to 3.6V Output
PRELIMINARY
The APC12 Centauri II series is Astec’s recent addition to its non-isolated SMT POL line. With the wide
acceptance of it’s predecessor (APC08 series) and the continuous system requirement for higher load current, the
Centauri platform have been revolutionized to provide 12A load current from it’s original 8A device. The APC12
offers the same standard features common to the Centauri Product Line: wide input voltage range; wide output
voltage range; high efficiency; Positive Output Enable; Power Good signal and Current Sharing. It also adapts the
same Centauri SMT footprint for optimum user flexibility and multiple sourcing.
The APC12 also comes with an output Trim pin, which allows output adjustment from 0.9V to 3.6V through
external resistance programming. It works from a wide input voltage range of 1.8V to 13V and offers an extensive
array of output voltages starting from 0.9V to 3.6V. It is ideal for Point of Load applications and provides the most
flexibility for the ever-changing DSP and ASIC power requirements.

APC12 Centauri II
Basic Operation and Features
The APC08/12 Centauri family was designed specifically to address applications where on board distributed power with Pointof-Load Converters (Conversion needed as close to the IC, usually DSP’s and ASIC’s) is employed. With its wide range input
and flexible programmable output, any change in the load becomes very manageable with little to no impact on time to market.
All of the converters in this family are buck converters. The APC12x03 versions allow 1.8V to 6V input voltage and the
APC12x08 versions allow a 5.6V to 13V input with 14V max surge.
MODULE PIN ASSIGNMENT
There are 4 to 7 surface mount pins on a Centauri module. The availability of pins from individual modules is relevant
to its version / selected option.

When ordered with no options, the module comes with only 4 pins – VIN, Gnd, VOUT and Enable – AND IS
COMPATIBLE WITH OTHER LEADING MANUFACTURER’s FOOTPRINT. When the full-featured module is
required: with Output Trim; Active Current Share and Power Good Signal PINs, “-9MA” suffix is added to the
standard part number. Please refer to the Part Number Ordering Scheme for other options (including packaging).
Note: When using the trim function, this module offers much more trim flexibility than the competitive footprint and also
requires a jumper between the two footprints to be source compatible. Contact Factory for details.

Enable Pin (Standard configuration)
Pin P5 is functioned to enable the output voltage of a
module. If this pin is left open or connected to ≥ 4.1Vdc
up to 14Vdc, the module is turned on. On the other hand,
if this pin is connected to ground or to a voltage potential
from 0 to 0.8Vdc, the module is turned off. The enable pin
can source current up to 60µA max - suited for typical
open-collector transistors readily available in the market.
For TTL compatibility, Figure 3 shows a 7405 open
collector inverter IC utilized to function the Enable
feature. Other common chips that can do the function are
74S05; 74HCT05; non-inverting - 7407; 74S07; 74HC07.
If SMT packaging is preferred, Fairchild's Tiny Logic
NC7SZ05 or TI's Little Logic SN7SLVC1G06 comes in SOT23
or SC70 packages.
Figure 3. Output Voltage Enable function diagram.
Special Feature Pins (Options):
Trim Function (-9):
Pin P4 is used for output voltage adjustment. The output voltage can be trimmed through an external resistor or through an
external DC supply as described in the succeeding sections.
Method 1: External Trim Resistor.
By connecting an external resistor across P4 and P3 (Gnd), the voltage appearing on pin P2 (Vo) is adjusted to a higher value.
The output voltage of a module can be adjusted up to a maximum value of 3.3V (nominal) or 83% of the input voltage,
whichever is lower. By connecting an external resistor across P4 and P2, Vo is adjusted to a lower value. Only small
reductions, 2%, in voltage are recommended, as adjustment to lower voltages tends to affect the loop compensation of the
module.
Full range adjustment (from 0.9V to 3.6V) can be obtained from a module with the lowest Vo setpoint (0.9Vo).

To adjust Vo to a higher value, please refer to

Requiring to adjust output voltage from Vo = 0.9V to Vot = 1.8V. Vref = 0.87V and R1 = 3.09kΩ (from TABLE 1).
Based on Equation (1), Rt can be determined as 3.0kΩ.
To adjust Vo to a lower value, Rt should be connected between P4 and P2. Equation (2) provides the calculation for Rt.

(Vo − Vref )(Vot − Vref )

Vo = 3.3V, Vot = 3.234V, Vref = 0.87V, R2 = 1.13kΩ (from TABLE 1).
Based on Equation (1), Rt can be determined as 111.9kΩ.

Method 2: External DC Source
By connecting an external DC supply across P4 (Enable) and P3 (GND) through a limiting resistor Rt, (see Figure 5), output
voltage adjustment can also be achieved. Equation 3 provides the relationship between the External DC supply, Vt, and Vo
(where Vo is the desired output voltage).

Vo Adjustment to Lower Voltages. This method does not limit the recommended lower Vo adjustment to 2% as mentioned
on previous sections re: Vo adjustment through external trim resistor.
Example:
Module version: APC08G03-9 (3V to 6Vin, 2.5Vo).
Requiring to adjust the output voltage from Vo = 2.5V to 1.8V
Vo = 1.8V, Vref = 0.87V, R1 = 3.09kΩ, R2 = 1.69kΩ (from Table 1). Based on Equation (3), Vt = 3.0V.
Example:
Module version: APC08G03-9 (3V to 6Vin, 2.5Vo).
Requiring to adjust the output voltage from Vo = 2.5V to 0.9V
Vo = 0.9V, Vref = 0.87V, R1 = 3.09kΩ, R2 = 1.69kΩ (from Table 1). Based on Equation (3), Vt = 5.9V.
Vo Adjustment to Higher Voltages
Example:
Module version: APC08G03-9 (3V to 6Vin, 2.5Vo).
Requiring to adjust the output voltage from Vo = 2.5V to 3.3V
Vo = 3.3V, Vref = 0.87V, R1 = 3.09kΩ, R2 = 1.69kΩ (from Table 1). Based on Equation (3), Vt = -1.84V.
If application of negative voltage is not desired, the limiting resistor Rt can either be changed to a lower value (Rt = 1kΩ
Ω, such
that Vt = 0.60V per Equation 3), or use Method 1.

Power Good Signal Operation (Option (-9MA)):
PG pin provides an output signal indicating the Vout is
operational (TTL logic signal). It can sink current up to a max
of 5mA and can have a maximum external pull-up voltage of
6V. Please see recommended setup shown on Figure 6.
Figure 6. PGood setup.
Active Current Share Operation (Option (-9MA)):
Active Current share pin is compatible with like modules only (APC08 to APC08 or APC12 to APC12). Connecting this pin
directly with the same Pin from another module guarantees current sharing to within 40% to 60% Iout. Note that this pin is not
compatible with competitive modules that employ active current sharing.
To attain efficient current sharing between like modules, the following points are recommended:
a) The modules to be shared should be located as close as possible into the host card.
b) The copper tracks that connect Vo and GND should at least be 0.60" in width with at least 2 oz. Cu.

RECOMMENDED LOCATION FOR PICK AND PLACE
The flat top surface of the large inductor (topside of the board) provides a versatile and convenient way of picking up the
module (see Figure 56). A 6-7mm outside diameter nozzle from a conventional SMD machine is recommended to attain
maximum vacuum pick-up. Nozzle travel and rotation speed should be controlled to prevent this off-centered picked-up
module from falling off the nozzle. The use of vision recognition systems for placement accuracy will be very helpful.

REFLOW NOTES / RECOMMENDATIONS

2.
3.
Refer to the recommended Reflow Profile per
Figure 57. Profile parameters exceeding the
recommended maximums may result to
permanent damage to the module.
The module is recommended for topside
reflow process to the host card. For other
orientations, contact factory.
In the event that the module needs to be
desoldered from the host card, some pins
may be detached from the module.

PACKING AND SHIPPING
Standard packaging for the modules will be in tape and reel. Jedec-style tray packaging is also available (add suffix
"J" in pn). Please refer to the ordering information. Maximum number of modules in a reel is 250 pcs. The tray can
hold 35 modules max. Please refer to Figure 59 for the T&R carrier dimensions and Figure 60 for the tray dimensions.
