PG-SSOP-14
Description
The TLE8386-2EL is a boost controller with built in protection features. The main function of this device is to step-
up (boost) an input voltage to a larger output voltage. The switching frequency is adjustable from 100 kHz to
700 kHz and can be synchronized to an external clock source. The TLE8386-2EL features an enable function
reducing the shut-down current consumption to < 2 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 with external components for adjustment 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 over temperature shutdown.
