BD28C5xFJ-LB PWM Types, DC/DC Converter ICs

This IC from ROHM Semiconductor is a top-ranked product for the industrial equipment market and is designed 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 low-power-consumption electrical converters. It has a lineup of V_DD UVLOs that support both Si and SiC MOSFETs. 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 an external resistor and capacitor on the RTCT pin.
