View   View TPS51125EVM

The TPS51125 is a cost effective, dual-synchronous buck controller targeted for notebook system power supply solutions. It provides 5V and 3.3V LDOs and requires few external components. The 270kHz 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. The TPS51125 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. Adaptive on-time D-CAP™ control provides convenient and efficient operation. The part operates with supply input voltages ranging from 5.5V to 28V and supports output voltages from 2V to 5.5V. TPS51125EVM evaluation module is a high efficiency, dual synchronous buck converter providing 5V at 8A and 3.3V at 8A from 8V to 25V input.
