Description

General part information

TLF42772 Series

The adjustable output voltage makes the TLF4277-2EL capable of supplying the majority of standard active antennas such as:• FM/AM• DAB• XM• SIRIUSFor an input voltage up to 40 V the TLF4277-2EL provides an adjustable output voltage in a range from 5 V up to 12 V. The integrated current monitor function is a unique feature that provides diagnosis and system protection functionality. Fault conditions such as overtemperature and output overvoltage are monitored and indicated at the current sense output. The maximum output current limit of the device is adjustable to provide additional protection to the connected load.Via the enable function the IC can be disabled to lower the power consumption.The PG-SSOP-14 EP package provides an enhanced thermal performance within an SO8 body size. TheTLF4277-2LDis the alternative available in the PG-TSON-10 package, which is a 3.3mm x 3.3mm leadless package with excellent thermal performance and the capability for AOI.
