Регуляторы напряжения - Импульсные регуляторы TPS54626PWP .

Импульсный понижающий DC-DC стабилизатор , регулируемый, 4.5В-18В (Vin), 760мВ-5.5В, 6.5А, HTSSOP-14

The TPS54626PWP is an adaptive on-time D-CAP2™ mode synchronous Buck Converter for use with digital set-top box (STB). The TPS54626 enables system designers to complete the suite of various end equipment's power bus regulators with low component count and low standby current solution. The main control loop for the TPS54626 uses the D-CAP2™ mode control which provides a very fast transient response with no external components. The adoptive on-time control supports seamless operation between PWM mode at heavy load condition and reduced frequency operation at light load for high efficiency. The TPS54626 also has a proprietary circuit that enables the device to adopt to both low equivalent series resistance (ESR) output capacitors, such as SP-CAP and ultra-low ESR ceramic capacitors. The device operates from 4.5 to 18V VIN input power supply voltage. The output voltage can be programmed between 0.76 and 5.5V. The device also features an adjustable soft-start time and a power go
