Introduction

AI Translation

The TPS51285A and TPS51285B are cost-effective dual-channel synchronous buck controllers with 5V and 3.3V LDOs, targeting notebook computer system power supply solutions. This device achieves low power consumption by using automatic skipping and ULQ™ modes, which helps to extend the battery life in the system's standby mode. It provides a 256kHz VCLK output to drive an external charge pump, thereby generating the gate drive voltage for the load switch with the lowest power consumption in the main converter. This device uses the adaptive on-time D-CAP™ mode control to achieve fast load transient response without an external compensation network. The TPS51285A/B operates with a power supply input voltage ranging from 5V to 24V and supports output voltages of 5V and 3.3V. The TPS51285A and TPS51285B come in a 20-pin, 3mm×3mm, QFN package and are rated for an operating temperature range of -40°C to 85°C.
