Part Number: TPS61202
I'm using the chip in a power bank design with a single Li-pol battery to drive 5V out for phone charging. It works fine with 20mA LED load (around 5.6V) but smokes the chip and inductor when a phone is connected (high load). I'm not an experienced power designer. Did I do something dumb?

In reply to Jasper Li:
Thanks for taking a look Jasper. Here's the BOM + layout. I know the layout could be improved - it's a first proto. I'm baffled why a heavy load causes the chip to lock up and smoke the inductor. I'm testing on a bench supply because the safety PCB in my 200mAh Li-pol battery would shut down when the circuit shorted out. It's really tedious to replace the chip - I use a heat gun and low melting point solder paste (Chipquik SMDLTLFP).
