Infineon TLE83862ELXUMA1, Boost Controller 8-Channel 14-Pin, PG-SSOP-14

The Infineon Basic smart boost controller with built in protection features. The main function of this device is to boost (step-up) an input voltage to a higher output voltage. The switching frequency is adjustable from 100 kHz to 700 kHz and can be synchronized with an external clock. The TLE8386-2EL features an enable function reducing shut-down current consumption to less than 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 harsh automotive environment and provides output overvoltage protection and overtemperature shutdown.
