4-V to 18-V, 3-A synchronous SWIFT™ step-down converter | RPY | 14 | -40 to 150

The TPS543320 is a

high-efficiency 18-V, 3-A synchronous buck converter employing an

internally-compensated, fixed-frequency Advanced Current Mode control. The device is

capable of providing high efficiency while running at a switching frequency up to

2.2 MHz. The device is in a small 2.5-mm × 3-mm HotRod™ VQFN package, which coupled with high efficiency at high frequency,

makes it optimal for designs requiring a small solution size. The fixed frequency

controller can operate from 500 kHz to 2.2 MHz and can be synchronized to an

external clock using the SYNC pin. Additional features include a high accuracy

voltage reference, selectable soft start times, montonic start-up into pre-biased

outputs, selectable current limits, adjustable UVLO through the EN pin, and a full

suite of fault protections.
