DESCRIPTION

The TPS51225/B/C 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 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, DCAP™ 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, 3 mm × 3 mm, QFN package and is specified from –40°C to 85°C.

(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2) All voltage values are with respect to the network ground terminal unless otherwise noted

(3) Voltage values are with respect to SW terminals.
