TI TPS51275CRUKR

降压同步（2），线性（LDO）（2）4控制器5V ~ 24V

Overview

The TPS51275, TPS51275B and TPS51275CRUKR are cost-effective, dual-synchronous buck controllers 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. The TPS51275, TPS51275B and TPS51275CRUKR 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 V to 24 V and supports output voltages of 5.0 V and 3.3 V. The TPS51275, TPS51275B and TPS51275CRUKR are available in a 20-pin, 3 mm x 3 mm, QFN package and is specified from –40°C to 85°C.
