6-PAKs 6-PAK POWER ELECTRONICS DIVISION SERIES PROGRAMMABLE DC/DC CONVERTER www.cdtechno.com POWER: 6 Amp click on Power Electronics Parrallelable Boost Modules SIZE: 2.00” x 0.60” x .27” PRODUCT DA DATTA SHEET OBSOLETE PRODUCT Contact Factory for Replacement Model DESCRIPTION FEATURES Small SIP Design Parallelable Boost SIP One stocking part meets a variety of loads Programmable Control SIP Control/Boost Pair extremely configurable Fast Transient Response No need for large external capacitors Extremely small footprint Low Component Count Low cost, high reliability Staked Pins Wave solderable Integrated Input Filter Low input ripple The 6-PAK™ is a modular system of control and boost SIPs. Each 6A control SIP can also drive up to 8 additional 6A boost SIPs in parallel, for a total of 54A. Each SIP accepts a regulated 5V input (+10%) and provides 2.5V to 3.6Vdc output. The circuit is optimized for high efficiency and fast load transient response needed by telecom, DSP and microprocessor applications. Advanced thermal design, monolithic power circuitry and synchronous rectification result in outstanding performance and value. With integrated input filter and output capacitors, the 6-PAK system makes a complete power supply which requires no external components over the specified operating range. Pins are staked for wave solderability.

Page 2 6-PAK 8/2001 REV F Programming The 6-PAK™ is programmed through the Control SIP. All connected Power Boosters follow the Control SIP programming. To program the 6-PAK™ for Vout<3.3, connect a resistor across the TRIM and Vo pins. For Vout>3.3, resistor is connected across TRIM and GND.

For thermal performance, the unit was mounted on a 4”x4” PCB (with ground plane) & enclosed in a box so that it operates in a controlled environment. 6-PAK 8/2001 REV F Page 3 Mechanical Outline TOLERANCES +.008” for 3 place decimals + .02” for 2 place decimals + .002” for pin diameter Pin Out Pin 1 2 3 4 5 6 7 8 9 System Interconnection Guidelines Function Vo Vo TRIM GND INTI Gnd INT2 Vi Vi Description Output Voltage Output Voltage Output Adjust* Ground InterModule 1 Ground InterModule 2 5V Input Voltage 5V Input Voltage * not connected on Boosters 1. Each SIP must have input, ground and output pins sunk into common input ground and output planes in the host PC board. 2. Two additional common signal traces are required to interconnect INT1 and INT2 pins. These traces must be a least 0.06” wide and make a straight connection among the modules. 3. Power Booster SIP must be adjacent to the Control SIP located in the center of the layout, as shown in the Typical Example figure. Recommended distance between SIP pin centers is 0.5”. 4. A 300 LFM air flow is required in direction from Pin 9 to Pin 1, to draw rated power from booster configuration. Each application using boosters should be evaluated for thermal performance.
