This product family provides up to 4A of output current or 20W of output power in an industry standard, compact, IC-like, molded package. It is highly integrated and does not require external components to provide the point-of-load function. A copper pad on the back of the module, in close contact with the internal heat dissipation components, provides excellent thermal performance. The assembly process of the modules is fully automated with no manual assembly involved. These converters possess outstanding electrical and thermal performance, as well as extremely high reliability under highly stressful operating conditions. IPM12C operates from an 8V~14V source and provides a programmable output voltage of 0.9V to 5V. The IPM product family is available in both a SMD or SIP package.

Current is measured at the input of the module. Figure 25: Input reflected-ripple current test setup To maintain low-noise and ripple at the input voltage, it is critical to use low ESR capacitors at the input to the module. Figure 28 shows the input ripple voltage (mVp-p) for various output models using 2x47 uF low ESR tantalum capacitors (SANYO P/N:16TPB470M, 47uF/16V or equivalent) or 2x22 uF very low ESR ceramic capacitors (TDK P/N:C3225X7S1C226MT, 22uF/16V or equivalent).

When the module is not soldered (via socket), place Kelvin connections at module terminals to avoid measurement errors due to contact resistance. The power module should be connected to a low ac-impedance input source. Highly inductive source impedances can affect the stability of the module. An input capacitance must be placed close to the modules input pins to filter ripple current and ensure module stability in the presence of inductive traces that supply the input voltage to the module. η =( Vo × Io ) × 100 % Vi × Ii 7 DS_IPM12C0A0R04_08242006 DESIGN CONSIDERATIONS Safety Considerations For safety-agency approval the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standards. For the converter output to be considered meeting the requirements of safety extra-low voltage (SELV), the input must meet SELV requirements. The power module has extra-low voltage (ELV) outputs when all inputs are ELV. The input to these units is to be provided with a maximum 10A time-delay fuse in the ungrounded lead.
