With quiescent currents of 1.6 µA under load (1.2µA at no load) in Burst Mode, the LTC3130 and LTC3130-1 synchronous current mode buck-boost converters deliver up to 600 mA of continuous output current from a wide variety of input sources. Their 2.4V to 25V input voltage range and 1V to 25V output range (LTC3130 is adjustable) provide a regulated output with inputs above, below or equal to the output. Via a proprietary buck-boost topology, the LTC3130/-1 provides low noise, jitter-free switching through all operating modes. Other shared features include a programmable maximum power point control (MPPC) capability. The LTC3130-1 additionally offers four user-selectable fixed output voltages: 1.8V, 3.3V, 5V and 12V, eliminating the resistor divider required for the adjustable output version. The LTC3130 and LTC3130-1 are available in thermally enhanced 20-lead 3mm x 4mm QFN and 16-lead MSOP packages with E- and I-grade devices specified over a -40°C to +125°C operating temperature range. E-grade pricing starts at $3.35 each/1,000 pieces for both packages. For more information, visit http://www.linear.com/product/LTC3130
