LTC31xx Synchronous Buck-Boost DC-DC Converters

Analog Devices Inc. LTC31xx Synchronous Buck-Boost DC-DC Converters are high-efficiency, ultra-low noise, and excellent for wireless long-life applications. The LTC3130 (600mA) and LTC3129 (200mA) have wide V_IN and V_OUT ranges and a 1.2MHz PWM architecture that minimizes the solution footprint.
