TPS51125ARGER Integrated Circuit Chip Synchronous Buck Controller IC Step Down Controller

TPS51125ARGER Integrated Circuit Chip Synchronous Buck Controller IC Step Down Controller​

Product Description Of TPS51125ARGER

TPS51125ARGER is a cost effective, dual-synchronous buck controller targeted for notebook system power supply solutions. It provides 5-V and 3.3-V LDOs and requires few external components. The 270-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’s efficiency.

TPS51125ARGER supports high efficiency, fast transient response and provides a combined power-good signal. Out-of-Audio mode light-load operation enables low acoustic noise at much higher efficiency than conventional forced PWM operation.
