BD28C57LFJ-LB
PWM Types DC/DC Converter IC
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.
