iAF Series DC/DC Power Modules

4.5-14V Input, 20A Output

Surface Mount Power Module

iAF power modules perform local voltage conversion from any bus

voltage in the 5V to 12V range. The iAF12020A007V utilizes a

low component count that results in both a low cost structure and

a high level of performance. The open-frame, compact, surface

mountable design features a low profile and weight as well as

additional edge plated pads that allow for extremely flexible and

robust manufacturing processes.

Advance Data Sheet: iAF Series – Non-isolated SMT Power Module Soldering Information: iAF surface mountable power modules are intended to be compatible with standard surface mount component soldering processes and either hand placed or automatically picked and placed. The figure below shows the position for vacuum pick up. The maximum weight of the power module is 5.5g (0.194 oz.). Improper handling or cleaning processes can adversely affect the appearance, testability, and reliability of the power modules.

Advance Data Sheet: iAF Series – Non-isolated SMT Power Module Thermal Management: An important part of the overall system design process is thermal management; thermal design must be considered at all levels to ensure good reliability and lifetime of the final system. Superior thermal design and the ability to operate in severe application environments are key elements of a robust, reliable power module. A finite amount of heat must be dissipated from the power module to the surrounding environment.
PAGE 15
Advance Data Sheet: iAF Series – Non-isolated SMT Power Module Operating Information: Over-Current Protection: The power modules have short circuit protection to protect the module during severe overload conditions. During overload conditions, the power modules may protect themselves by entering a hiccup current limit mode. The modules will operate normally once the output current returns to the specified operating range.

Advance Data Sheet: iAF Series – Non-isolated SMT Power Module Output Voltage Adjustment: The output voltage of the power module may be adjusted by using an external resistor connected between the Vout trim terminal and GND terminal. If the output voltage adjustment feature is not used, trim terminal should be left open. Care should be taken to avoid injecting noise into the power module’s trim pin Vout (V) Ru (Kohm) 0.7 690 1.2 13.5 1.5 8.52 1.8 6.21 2.5 3.81 3.3 2.64 5.0 1.
