General Description

The TPS51225/B/C is a cost-effective, dualsynchronous buck controller targeted for notebook system-power supply solutions.

It provides 5-V and 3.3-V LDOs and requires few external components.

The 260-kHz VCLK output can be used to drive an external charge pump, generating gate drive voltage for the load switches without reducing the main converter efficiency.
