Description

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. The built-in 650V startup circuit contributes to low power consumption. 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 is 25kHz by a fixed method. A built-in frequency hopping function also contributes to low EMI. A built-in 650V switching MOSFET makes designs easy.
