The PT7126A with Switching Controllers SOP7 RoHS is a highly integrated high-efficiency voltage converter IC developed by PUOLOP. This chip is a two-phase synchronous buck converter, which ensures high performance of voltage conversion. It comprises of various components such as two master/slave current loop & high-speed low-noise current-mode control loop for two-phase operation. Moreover, it features high-efficiency (>97%), a wide input voltage range from 4V to 28V, a high-performance high-speed PWM (pulse-width modulation) modulator, adjustable operating frequency up to 1.3MHz, excellent loop performance, and various protection functions such as over-current, under-voltage protection. Furthermore, it is packaged in an SOP7 surface mount package that is compliant with the RoHS (Restriction of Hazardous Substances) standard. Thus, it is ideal for a wide variety of power-supply applications.
