MODEL: APC08 SERIES OCTOBER 4, 2004 - REVISION 03 SHEET 6 OF 23 Technical Reference Note (APC08) 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 to its version / selected option.

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.

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, MODEL: APC08 SERIES OCTOBER 4, 2004 - REVISION 03 SHEET 8 OF 23 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. Rt = Vref R1 Vot − Vo Equation (1) Figure 4. Output Voltage Trim Setup. Please refer to related constants given in TABLE 1 to calculate the Equation.

Example: Module version: APC08J03-9 (1.8 to 6.0Vin, 0.9Vo). Requiring to adjust output voltage from Vo = 0.9V to Vot = 1.8V. Vref = 0.875V 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. Rt = (Vo − Vref )(Vot − Vref ) Vref (Vo − Vot ) R2 Equation (2) Note: minimum Vo = 0.9V MODEL: APC08 SERIES OCTOBER 4, 2004 - REVISION 03 SHEET 9 OF 23 Technical Reference Note (APC08) Method 1: External Trim Resistor (continued) Example Module version: APC08F03-9 (4.0 to 6.Vin, 3.3Vo). Requiring to adjust the output voltage from Vo = 3.3V to Vot = 3.3 (1-0.02) = 3.234V. Vo = 3.3V, Vot = 3.234V, Vref = 0.875V, R2 = 1.13kΩ (from TABLE 1). Based on Equation (1), Rt can be determined as 111.9kΩ. Trim Function (continued) 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).

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, Vr = 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, Vr = 0.87V, R1 = 3.09kΩ, R2 = 1.69kΩ (from Table 1). Based on Equation (3), Vt = 5.9V. MODEL: APC08 SERIES OCTOBER 4, 2004 - REVISION 03 SHEET 10 OF 23 Technical Reference Note (APC08) Method 2: External DC Source (continued) 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, Vr = 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, 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.

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 240 RECOMMENDED REFLOW PROFILE 220 200 1. 2. 3.
