The Texas Instruments TPS53318DQPT is a high-efficiency, synchronous buck converter designed for power management applications. It supports an input voltage range from 1.5V to 22V and can deliver up to 8A of continuous output current. The output voltage is adjustable, ranging from 0.6V to 5.5V, making it versatile for various power supply designs.
This device features a D-CAP mode for fast transient response and selectable switching frequencies from 250kHz to 1MHz. It includes integrated power MOSFETs and a boost switch, simplifying external component count. The converter also offers an Eco-mode for improved light-load efficiency, with a shutdown current of less than 110µA.
The TPS53318DQPT is available in a 22-LSON-CLIP (6x5) surface mount package. It operates within a temperature range of -40°C to 85°C (TA). The device is suitable for applications requiring efficient and compact DC-DC conversion.
Key electrical characteristics include a 1.5V to 22V input voltage range, an 8A output current capability, and an adjustable output voltage from 0.6V to 5.5V. The switching frequency can be set between 250kHz and 1MHz. It also includes a built-in 0.6V reference and selectable soft-start times.
