• Single-Device 5V to 3V Power
• 85% Efficiency
• Small SIP Footprint
• Adjustable Output Voltage The PT6400 is a high performance +5V to +3.3V, 3 Amp, 12-Pin SIP (Single In-line Package) Integrated Switching Regulator (ISR) designed for stand alone (not parallelable) op- eration. This high-performance ISR allows easy integration of low-power 3.3V logic IC’s into existing 5V systems without redesigning the central power supply. Only two external capacitors are required for proper operation. The out- put voltage is easily adjustable with one external resistor. The PT6406,7,8 can be used to terminate high-speed data buses such as Futurebus (+2.1V) or the new GTL (+1.2V) logic buses. Please note that this product does not include short circuit protection.

For technical support and more information, see inside back cover or visit www.ti.com/powertrends PT6400 Series Adjusting the Output Voltage of the PT6400 Series 3AMP 5V Bus Converters The output voltage of the Power Trends PT6400 Series ISRs may be adjusted higher or lower than the factory trimmed pre-set voltage with the addition of a single external resistor. T able 1 accordingly gives the allowable adjustment range for each model in the series as V a (min) and Va (max). Adjust Up: (See note 1) An increase in the output voltage is obtained by adding a resistor R1, between pin 12 (V o adjust) and pins 9-11 (Vout). Adjust Down: (See note 1) Add a resistor (R2), between pin 12 (Vo adjust) and pins 5-8 (GND). Refer to Figure 1 and T able 2 for both the placement and value of the required resistor; either R1 or (R2) as appropriate. Notes: 1. The direction in which each resistor adjusts the output of the PT6400 series differs from many other Power Trends products. These output voltage adjustment notes are therefore specific only to the PT6400 models. 2. Use only a single 1% resistor in either the R1 or (R2) location. Place the resistor as close to the ISR as possible. 3. Never connect capacitors from V o adjust to either GND or Vout. Any capacitance added to the V o adjust pin will affect the stability of the ISR. 4. An increase in the output voltage may place additional limits on the input voltage range of the part. The revised minimum input voltage will be out + 1.2) or 4.5V , whichever is higher. Do not exceed 5.5Vdc. Figure 1 The values of R1 [adjust up], and (R2) [adjust down], can also be calculated using the following formulae. 12.45 VoR1 = (Va – Vo) – 49.9 k Ω 12.45 (2Va – Vo) – 49.9 k Ω(R2) = Vo – Va Where: V o = Original output voltage Va = Adjusted output voltage Table 1 PT6400 ADJUSTMENT RANGE Series Pt # PT6408 PT6404 PT6406 PT6407 PT6409 PT6405 Adjust Up 100 µF 100 µF Vo COMCOM Vin (R2) Adj Down PT6400 9,10,11 125,6,7,8 2,3,4 Vin Vo GND Vo(adj)

Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
