DATASHEET
TD1519
General Description
Features
The TD1519 is a monolithic synchronous buck •
regulator. The device integrates two 90mΩ •
MOSFETs, and provides 2A of continuous load current •
over a wide input voltage of 4.75V to 32V. Current •
mode control provides fast transient response •
and cycle-by-cycle current limit.
•
An adjustable soft-start prevents inrush current at •
turn-on, and in shutdown mode the supply current
drops to 1µA.
•
This device, availablein an SOP8-PP package, •
provides a very compact solution with minimal external •
components.
