... Si9161 Vishay Siliconix PIN CONFIGURATIONS PIN DESCRIPTION Pin The positive power supply for all functional blocks except output driver. A bypass capacitor of 0.1 µF (minimum) is recommended. Pin logic high on this pin allows normal operation. A logic low places the chip in light-load optimized-efficiency mode. In light-load mode, the oscillator frequency is reduced and D goes high, disabling synchronous rectification ...

... Si9161 Vishay Siliconix OPERATION OF THE Si9161 BOOST CONVERTER The Si9161 combined with optimized complementary MOSFETs provides the ideal solution to small, high efficiency, synchronous boost power conversion. Optimized for a 1-cell lithium ion, or 3-cell to 4-cell Nickel metal hydride battery capable of switching at frequencies MHz. Combined ...

... Si9161 Vishay Siliconix Stability Components A voltage mode boost converter is normally stabilized with simple lag compensation due to the additional 90 phase lag introduced by the additional right hand plane zero, as well as having a duty factor dependent resonant frequency for the output filter. The stability components shown in Figure 1 have been chosen to ensure stability under all battery conditions while maintaining maximum transient response ...

... Figures 7 through 9 show the output noise and output spectrum analysis. Output Noise Spectrum Note there is no random noise, only switching frequency harmonics. This is very good news for the RF stages, where an unknown, or random noise spectrum will cause problems. -th of the Si9161 Vishay Siliconix S-60752—Rev. B, 05-Apr-99 11 ...

... Si9161 Vishay Siliconix Conclusion Switching at high, known frequencies results in a smaller footprint while maintaining high efficiency. Efficiencies at high switching frequencies can be improved by using Si6801 optimized low gate charge and low gate resistance MOSFET. Even though the high frequency MOSFET has been designed with minimum gate charge, it still presents significant power loss during the light load conditions ...
