TEST CONFIGURATIONS DESIGN CONSIDERATIONS Input Source Impedance L VI(+) 2 100uF Tantalum BATTERY VI(-) Note: Input reflected-ripple current is measured with a simulated source inductance. Current is measured at the input of the module. Figure 29: Input reflected-ripple 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.
DESIGN CONSIDERATIONS (CON.) FEATURES DESCRIPTIONS 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.
FEATURES DESCRIPTIONS (CON.) Vtrim 0.7 0.1698 Vo 0.7525 Over-Temperature Protection For example, to program the output voltage of a DNL module to 3.3 Vdc, Vtrim is calculated as follows The over-temperature protection consists of circuitry that provides protection from thermal damage. If the temperature exceeds the over-temperature threshold the module will shut down. The module will try to restart after shutdown.
FEATURE DESCRIPTIONS (CON.) The amount of power delivered by the module is the voltage at the output terminals multiplied by the output current. When using the trim feature, the output voltage of the module can be increased, which at the same output current would increase the power output of the module. Care should be taken to ensure that the maximum output power of the module must not exceed the maximum rated power (Vo.set x Io.max ≤ P max).
FEATURE DESCRIPTIONS (CON.) Sequential Start-up Ratio-Metric Sequential start-up (Figure 40) is implemented by placing an On/Off control circuit between VoPS1 and the On/Off pin of PS2. Ratio–metric (Figure 42) is implemented by placing the voltage divider on the TRACK pin that comprises R1 and R2, to create a proportional voltage with VoPS1 to the Track pin of PS2. For Ratio-Metric applications that need the outputs of PS1 and PS2 reach the regulation set point at the same time.
THERMAL CONSIDERATIONS Thermal management is an important part of the system design. To ensure proper, reliable operation, sufficient cooling of the power module is needed over the entire temperature range of the module. Convection cooling is usually the dominant mode of heat transfer. Hence, the choice of equipment to characterize the thermal performance of the power module is a wind tunnel.
