Claiming to have one of the highest operating efficiencies in the industry, the Si9168BQ buck or boost controller IC operates with 95% efficiency under its full rated load and in the 80% range for lighter loads. When applied in a buck configuration, the device converts input voltages between 5 V and 10 V to an output voltage as low as 1.3 V. In boost configuration, input voltages as low as 5 V can be boosted up to 12.6 V. It is also claimed that the device can provide regulated power to analog, DSP, filtering and RF circuitry. Packaged in a 16-pin TSSOP, the Si9168BQ can operate from dual-cell lithium ion batteries and is compatible with TDMA, CDMA, GSM and PCS power amplifiers. Pricing for the device starts at $1.50 each/100,000.
