Centauri (APC08) Non-Isolated DC/DC Power Module

The Centauri (APC08) DC-DC Power Module is a high efficiency non-isolated buck converter designed for use in a wide

variety of applications. It works from a wide input voltage range of 1.8V to 6V or 5V to 13V and offers an extensive array of

output voltages starting from 0.9V to 3.6V (up to 6V in some flavors). Through careful layout and component selection it

achieves the highest efficiency/load in the smallest footprint available in the market today. It is ideal for Point of Load

applications and provides the most flexibility for the ever-changing DSP and ASIC power requirements.

Basic Operation and Features

The APC08 family was designed specifically to address applications where on board distributed power with Point-of-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 APC08x03 versions allow 1.8V to 6V input voltage and the

APC08x08 versions allow a 5V to 12V 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

INDUSTRY STANDARD PINOUT

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. The PGood, Active Current Share, and Trim pins are options that can be

ordered with any model number. For the optional trim function add a (-9) to the end of the standard part number. For

the optional current share and PGood signal in addition to the trim function, add (-9MA) to the end of the part

number. Please refer to the Part Number Ordering Scheme section.

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 applications note.

Typical Application Circuit (Standard Pinout)

Recommended C1 is a low ESR (<100 mohms) 100 µF tantalum and C2 is a 1 µF ceramic or equivalent. Recommended

output decoupling capacitor C3 for –W models is 22 µF low ESR ceramic capacitor (at a min). For all other models, C3 can go

as low as 1 µF ceramic capacitor.

Figure 2. Typical Application Circuit.

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 60mA 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.

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,

MODEL: APC08 SERIES

SHEET 8 OF 23

OCTOBER 4, 2004 - REVISION 03

Technical Reference Note (APC08)

Method 1: External Trim Resistor (continued)

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

Figure 4. The required resistor value (Rt) can be

determined through Equation (1) where Vo is the

voltage on P2 before the adjustment and Vot is the

voltage of P2 after Rt is connected.

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 = 3.3V, V = 0.87V, R₁= 3.09kW, R₂= 1.69kW (from Table 1). Based on Equation (3), Vt = -1.84V.

r

If application of negative voltage is not desired, the limiting resistor Rt can either be changed to a lower value (Rt = 1kW, 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.

For multiple module configurations, the PG pin/signal

can be used to drive the Enable signal of the other

module for simple sequencing scheme.

Figure 6. PGood setup.

Active Current Share Operation (Option (-9MA)):

Active Current share pin is compatible with APC08 modules only. 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.

c) Due to tolerances of turn-on time characteristics, the initial load current of two APC08 units connected in current sharing

configuration should be less than the OCP point of one module. This is to ensure that the first unit that reaches Vo set-point

is capable of supplying the load current. This also eliminates the possibility of false triggering the OCP protection. The load

current can then be ramped up to the desired loading condition (typical 13A max combined for 2 modules in parallel) after

both outputs have stabilized.

d) Due to mismatches on the output voltage setpoints of the two converters in parallel, it is recommended to maintain a

minimum load current (typical 1.5A) on the output.

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 46). 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.

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 300pcs. The tray can

hold 33 modules max. Please refer to Figure 49 for the carrier dimensions.

All dimensions are in mm
