Visão Geral
Description
The converter integrates a 1.5 MHz fixed-frequency operation, allowing for smaller external components and a compact overall solution size. It includes a power-save mode to improve efficiency at light loads, and its low quiescent current further reduces power consumption in standby conditions.
Protection features such as thermal shutdown, overcurrent protection, and undervoltage lockout enhance reliability and robustness. The TPS628501DRLR is housed in a small 2 mm x 2 mm, 6-pin SOT-563 package, making it an ideal choice for space-constrained applications in consumer electronics, industrial equipment, and more.
