Am attempting to repair an automotive wireless phone charger, which has a burnt IC. Appears to be a power management device, with direct input from 12VDC source on pin#2. One section of the top is burnt, which has obscured some of the markings. Has a large U logo. 4 pins, SOIC pkg.
First line marked 034B1 (unsure of first two characters, 3 could be an 8, and 0 could be top of a 2 or 3).
Second line has 3476 as ending characters, prefix is missing. Suspect that this is a V reg or PWM controller of some sort.
