this product is a rank product for the industrial equipment market. this is the best product for use in these applications. the pwm type dc/dc converter for ac/dc provides an optimal system for all products that require an electrical outlet. this ic supports both isolated and non-isolated devices and enables simpler designs of various types of a low power consumption electrical converters. this ic has a lineup of vdd uvlo that support both si and sic of mosfet. power supplies can be designed flexibly by connecting a current detection resistor for the switching externally. current is restricted in each cycle and excellent performances are demonstrated in a bandwidth and transient response since a current mode control is utilized. the switching frequency can be set by external resistor and capacitor on the rtct pin.
