The working principle of RT6204GSP is based on Buck-Boost topology. It has two high-side MOSFETs and two low-side MOSFETs connected in the synchronous rectifier configuration.The working frequency of the IC is typically 500KHz. A current-mode control loop is used to control the output voltage. This current mode control loop has two parts, the internal loop and the external loop. The internal loop senses the output current and is responsible for the current limitation and short-circuit protection. The external loop compares the output voltage and the voltage reference to determine the duty cycle of the switching operation. The external loop also uses the current mode to provide better load and line regulation characteristics. The IC also has a built-in soft-start function, to reduce current surges during startup.
