TPS61236P: Inquire about the Vout-Vin spec.

Part Number: TPS61236P

Hi TI experts,

TPS61236's Vin spec is max Vout-0.6V. 

However, my customer designed it with the following specifications.

Vin : 3.5~4.2V

Vout : 4.5V

When Vin is 4.2V, the voltage difference between Vout and Vin is 0.3V. this is TPS61236 spec out.

In this case, is there a possibility that the IC will fail?

Pin2 (SW) and Pin9 (Vout) short defects occurred. (Pin2 to Pin9 : 20~25ohm)

Please give me your technical opinion.

Thanks,

Downey Kim.
