BM2P26CK-Z
PWM Type DC/DC Converter IC with Integrated Switching MOSFET

The PWM Type DC/DC converter for AC/DC provides an optimal system for all products that include an electrical outlet. The built-in 650V startup circuit contributes to low power consumption. Small-sized power supplies can be designed with a built-in current detection resistor for switching. Current is restricted in each cycle and excellent performance is demonstrated in bandwidth and transient response since current mode control is utilized. The switching frequency is 100kHz by a fixed method. At light load, the switching frequency is reduced and high efficiency is achieved. A built-in frequency hopping function also contributes to low EMI. A built-in 800V super junction MOSFET makes designs easy.
