LINEAR(LINT) LTC3769EFE 60V, low IQ, synchronous boost converter controller.

About:

The LTC3769 is a high-performance, single-output, synchronous boost converter controller for driving full n-channel power MOSFETs. Its synchronous rectification improves efficiency, reduces power losses, and reduces heat dissipation requirements, simplifying high-power boost applications. The 28μA no-load static current extends uptime in battery-powered systems.

The 4.5V to 60V input power range covers a wide range of system architectures and battery chemistry. When bias is applied from the output of the boost converter or another auxiliary power supply, the LTC3769 can operate with an input power supply as low as 2.3V after startup. The operating frequency of the device can be set in the range of 50kHz to 900kHz or synchronized to an external clock using an internal PLL.
