Description
The TLE8386EL is a 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.
