نظرة عامة على المنتج
The TPS63802DLAR is a 2A high-efficiency, low-Iq non-inverting buck-boost converter from Texas Instruments. It operates over a wide input voltage range of 1.3V to 5.5V and provides an adjustable output from 1.8V to 5.2V. The device uses a peak current mode control with a 4-switch H-bridge topology, seamlessly transitioning between buck, buck-boost, and boost modes. Packaged in a HotRod QFN (DLA, 3x2mm), it achieves a tiny 21.5mm2 total solution size.
