Introduction

AI Translation

TPS51123A is a cost-effective dual synchronous buck controller designed for notebook system power solutions. It provides 5V and 3.3V LDO outputs and requires minimal external components. TPS51123A supports high efficiency, fast transient response, and provides a combined power-good signal. Out-of-Audio mode light-load operation at frequencies significantly higher than conventional forced PWM operation enables low audible noise. Adaptive on-time D-CAP control provides convenient and efficient operation. This device operates with a power input voltage range of 5.5V to 28V and supports output voltages from 2V to 5.5V. The TPS51123A is available in a 24-pin QFN package and is rated for an ambient operating temperature range of -40°C to 85°C.
