Introduction

AI Translation

The TPS51225/B/C is a cost-effective, dual synchronous buck controller designed for notebook computer system power supply solutions. It provides 5V and 3.3V LDOs and requires only a minimal number of external components. The 260kHz VCLK output can be used to drive an external charge pump to generate the gate drive voltage for the load switch without reducing the efficiency of the main converter. The TPS51225/B/C supports high efficiency, fast transient response and provides a combined power good signal. Adaptive on-time, D-CAP™ control enables convenient and efficient operation. This device operates with a power input voltage range between 5.5V and 24V and supports output voltages of 5.0V and 3.3V. The TPS51225/B/C comes in a 20-pin, 3mm x 3mm, QFN package and is rated for an operating temperature range of -40°C to 85°C.
