TD1519
General Description
Features
The TD1519 is a monolithic synchronous buck
regulator. The device integrates two 90m
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.
