TLE8386EL

The TLE8386EL is a high-side-sense boost controller with built in protection and diagnostic features. The main function of this device is step-up (boost) an input voltage to a larger output voltage. The diagnostics are communicated on a status output (pin ST) to indicate a fault conditions such as over temperature, open feedback and open load. The switching frequency is adjustable in the range of 100 kHz to 500 kHz and can be synchronized to an external clock source. The TLE8386EL features an enable function reducing the shut-down current consumption to <10 μA. The current mode regulation scheme of this device provides a stable regulation loop maintained by small external  compensation components. The integrated soft-start feature limits the current peak as well as voltage overshoot at start-up. This IC is suited for use in the harsh automotive environments and provides protection functions  such as output overvoltage protection and overtemperature shutdown.
