TPS1HB08-Q1: Does it have internal charge pump circuit?

Part Number: TPS1HB08-Q1

Hi team, 

Does TPS1HB08-Q1 have internal charge pump circuit?

How much switching frequency it is? 
When does charge pump operate or be disabled? (Ex. charge pump is enabled @ EN input voltage is H / it is disabled @ EN input is low...)

We are worried about its EMI characteristics

Regards,
Ochi
