The RT8116 is a low cost PWM controller with an integrated N-MOSFET gate driver for a single synchronous buck converter. The highly integrated 8-pin controller reduces size and cost of the power supply. The RT8116 can be used in a wide variety of applications, since it can work with either 5V or 12V supplies. It provides single feedback loop, voltage mode control with fast transient response. The output voltage can be precisely regulated to as low as 0.8V. Switching frequency is internally set at either 275kHz or 200kHz to save external component. The RT8116 also supports programmable soft-start function via an external capacitor. Protection features include programmable over current protection and under-voltage lockout (UVLO).
