Регуляторы напряжения - Импульсные регуляторы TPS542951PWP

Импульсный DC/DC стабилизатор , синхронный, двойной, 4.5В до 18В вход, 7В/2А, 700кГц, HTSSOP-16

The TPS542951PWP is a dual adaptive on-time D-CAP2™ mode synchronous Buck Converter 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 loops of the TPS542951 use the D-CAP2™ mode control which provides a very fast transient response with no external compensation components. The adaptive on-time control supports seamless transition between PWM mode at higher load conditions and Eco-mode™ operation at light loads. Eco-mode™ allows the TPS542951 to maintain high efficiency during lighter load conditions. The TPS542951 is able to adapt to both low equivalent series resistance (ESR) output capacitors such as POSCAP or SP-CAP and ultra-low ESR, ceramic capacitors. The device provides convenient and efficient operation with input voltages from 4.5 to 18V.
