TPS543320 Description
The TPS543320 is a high-efficiency 18-V, 3-A synchronous buck converter employing an internallypensated, fixed-frequency Advanced Current Mode control. It 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...
