Two new versatile DC/DC controller ICs, the LT®3757 and LT3758, are optimized for boost, flyback, SEPIC and inverting converter applications. The LT3757 operates over an input range of 2.9V to 40V, suitable for ap- plications from single-cell lithium-ion battery portable electronics up to high voltage automotive and industrial power supplies. The LT3758 extends the input voltage to 100V, providing flexible, high performance operation in high voltage, high power telecom- munications equipment. Both ICs exhibit low shutdown quiescent cur- rent of 1µA, making them an ideal fit for battery-operated systems. Both integrate a high voltage, low dropout linear (LDO) regulator. Thanks to a novel FBX pin architecture, the LT3757 and LT3758 can be connected directly to a divider from either the positive output or the negative out- put to ground. They also pack many popular features such as soft-start, input undervoltage lockout, adjust- able frequency and synchronization in a small 10-lead MSOP package or a 3mm × 3mm QFN package.

The LTC6930 is a self-contained, fully integrated all silicon oscillator that occupies a unique space within the world of clock solutions, providing a combination of accuracy and low power features that is hard to beat. It can accurately provide fixed frequencies between 32.768kHz and 8.192MHz over a wide supply range of 1.7V–5.5V without the need for additional external components. It typically dissipates between 100µA and 500µA depending on frequency and load.
