The TPS51225/B/C is a cost-effective, dual-sychonous buck controller targeted for notebook system-power supply solution.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. The TPS51225/B/C supports high efficiency, fast transient response and provides a combined power-good signal. Adaptive on-time, D-CAP control provides convenient and efficient operation. The device operates with supply input voltage ranging from 5.5 v to 24 V and supports output voltages of 5.0 V and 3.3 V. The TPS51225/B/C is available in a 20-pin, 3mm x 3mm, QFNpackage and is specified from -40°C to 85°C.
