The device is capable of providing up to 5.5V output, and the integrated power MOSFET has 2.7A (TYP) switch current limit. Output Voltage Configuration The SGM66051 supports output voltage up to 5.5V, and a resistor divider connected at FB pin is used to configure the output voltage. The resistive divider value is calculated via Equation 1. VOUT − VFB R1 VFB = Inductor Selection Inductor is an essential element for today’s DC/DC switch mode power supplies regardless of topology. Inductor serves as the energy storage element for power conversion. Inductance and inductor’s saturation current are two most important criterions for inductor selection. For general rule of thumb, the selected inductance should provide a peak to peak ripple current that is around 30% of the average inductor current at full load and nominal input voltage. The average inductor current for a Boost converter is the input current. Equation 2 shows the calculation of inductance selection, where f is the switching frequency, ΔIL is the inductor ripple current. VCC ΔIL × fSW  VIN   VO ×  1 - Output Capacitor The output capacitors of Boost converter dictate the output voltage ripple and load transient response. Equation 3 is used to estimate the necessary capacitance to achieve desired output voltage ripple. Where ΔV is the maximum allowed ripple. CMIN = (1) R2 For simplicity, 110kΩ is recommended for R2. A 1MΩ resistor for R1 configures the output voltage to 5V. L= between the VCC pin and GND pin of SGM66051. For the applications where the SGM66051 is located far away from the input source, a 47µF or higher capacitance capacitor is recommended to damp the wiring harness’s inductance.   I O × ( VOUT − VCC ) f × ΔV × VOUT (3) Again, the SGM66051 is an internally compensated device. The loop response is optimized for capacitor in the range of 4.7µF to 22µF. Due to the DC bias nature of ceramic capacitors, care should be taken by verifying manufacture’s datasheet to ensure enough effective capacitance at desired output voltage. Layout Guidelines In addition to component selection, layout is a critical step to ensure the performance of any switch mode power supplies. Poor layout could result in system instability, EMI failure, and device damage. Thus, place the inductor, input and output capacitors as close to the IC as possible, and use wide and short traces for current carrying traces to minimize PCB inductance. For Boost converter, the output capacitor’s current loop from VOUT pin back to the GND pin of the device should be as small as possible. (2) The selected inductor should have a saturation current rating higher than the 2.7A current limit of SGM66051. Lastly, the inductor affects the close loop response of the DC/DC converter. The SGM66051 is an internally compensated device with the loop response optimized for inductor in the range of 2.2µH to 10µH. Input Capacitor Boost converter’s input capacitor sees continuous current throughout the entire switching cycle. A 10µF ceramic capacitor is recommended to place as close as possible SG Micro Corp www.sg-micro.com Figure 5.
