Dear sir,
This is my first post on the forum.
I am a using the above part in my design of mother board for colibri V51 module.
The design is based on the colibri_arm_iris _carrier bord v1.1. The schematic is attached.
When apply 24v or 5v at Vin to the circuit. TPS51120 gets warm after some time.
Also I get 3.3 v at VREG3 pin but only 1.34v at VREG5 pin. Also 0.3 volts at VREF2.
Also no output at Pin 26 and 15.
Since I am using this part for the first time , please suggest the test procedure/possible cause for the problem.

Thanks...
