The LTC3130/LTC3130-1 expands Linear’s high performance line of low-quiescent current, medium voltage monolithic synchronous buck-boost converters. The LTC3130/LTC3130-1 delivers up to 600mA of continuous output current in buck mode. The device will start-up from input voltages as low as 2.4V and up to 25V. Once started, the converter can operate from input voltages below 1V, making it suitable for a wide variety of input sources. The output is programmable from 1V to 25V, seamlessly operating with input voltages above, equal to, and below the output. The low noise buck-boost topology incorporated in the LTC3130/LTC3130-1 provides jitter-free operation and continuous transitions through all of the operating modes, making it ideal for noise-sensitive applications. The LTC3130-1 shares all of the features of the LTC3130, but offers four fixed programmable output voltages: 1.8, 3.3, 5, and 15V. The LTC3130/LTC3130-1 is similar in design to the 15V/200mA low IQ LTC3129/LTC3129-1, significantly increasing the voltage and output current capability to target a wider range of applications while offering similar low IQ levels.
