OPTIREG switcher TLE8386-2EL Basic smart boost controller Features Wide input voltage range from 4.75 V to 45 V Constant current regulation Constant voltage regulation Very low shutdown current: I <2A q Flexible switching frequency range, 100 kHz to 700 kHz Synchronization with external clock source Available in a small thermally enhanced PG-SSOP-14 package Internal 5 V low drop out voltage regulator Output overvoltage protection External soft start adjustable by capacitor Overtemperature shutdown Green Product (RoHS) Compliant Potential applications Step up converter Voltage stabilization during cold cranking SEPIC Flyback converter Product validation Qualified for automotive applications. Product validation according to AEC-Q100. Description The TLE8386-2EL is a 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 A. 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.
