This article presents a PWM current mode DC-DC buck converter for wireless power receiver in MCR (Magnetic Coupling Resonance) WPT System. Simulations are based on 0.18μm BCD process in Towerjazz technology, 1-poly 3metal. The current mode controlled based DC-DC buck converter operates with 2MHz operating frequency. Power switch was designed with LDMOS of BCD process in order to withstand the high voltage and the high current. We also design a control block composed of the current sensor, comparator, OTA, PWM signal generator and gate driver. The proposed buck converter has an input voltage range 6-10V with maximum output current of 1A while providing 5V output.
