Регуляторы напряжения - Импульсные регуляторы TPS564208DDCT

Импульсный понижающий DC-DC стабилизатор , регулируемый, 4.5В-17В (Vin), 760мВ-7В/4A, 560кГц

The TPS564208DDCT is a 4.5V to 17V input, 4A synchronous step down voltage regulator in 6 pin SOT-23 package. This device is simple, easy-to-use and are optimized to operate with minimum external component counts and also optimized to achieve low standby current. The switch mode power supply (SMPS) device employ D-CAP2 mode control providing a fast transient response and supporting both low equivalent series resistance (ESR) output capacitors such as specialty polymer and ultra-low ESR ceramic capacitors with no external compensation components. It is used in digital TV power supply, high definition Blu-ray disc players, networking home terminal, digital set top box (STB) and surveillance.
