The TPS53319DQPT is a Synchronous Switcher with integrated power MOSFETs. It is designed for ease of use, low external component count and space-conscious power systems. This device feature accurate 1%, 0.6V reference and integrated boost switch. A sample of competitive features include 1.5 to 22V wide conversion input voltage range, very low external component count, D-CAP™ mode control for super fast transient, auto-skip mode operation, internal soft-start control and no need for compensation. The conversion input voltage range from 1.5 to 22V, the supply voltage range is from 4.5 to 25V and the output voltage range is from 0.6 to 5.5V.
