BM2P26CK-Z ROHM

Datasheet AC/DC Convertor IC PWM Type DC/DC Converter IC with Integrated Switching MOSFET BM2P26CK-Z General Description Key Specifications The PWM Type DC/DC converter for AC/DC provides an Operating Power Supply Voltage Range optimal system for all products that include an electrical VCC Pin Voltage: 11.9 V to 25.5 V outlet. DRAIN Pin Voltage: 800 V (Max) The built-in 650 V startup circuit contributes to low power VH Pin Voltage: 650 V (Max) consumption. Small-sized power supplies can be Current at Switching Operation: 0.6 mA (Typ) designed with a built-in current detection resistor for Current at Burst Operation: 0.35 mA (Typ) switching. Current is restricted in each cycle and Switching Frequency: 100 kHz (Typ) excellent performance is demonstrated in bandwidth and Operating Temperature Range: -40 C to +105 C transient response since current mode control is utilized. The switching frequency is 100 kHz by a fixed method. At Package W (Typ) x D (Typ) x H (Max) light load, the switching frequency is reduced and high DIP7K 9.27 mm x 6.35 mm x 8.63 mm efficiency is achieved. A built-in frequency hopping pitch 2.54 mm function also contributes to low EMI. A built-in 800 V super junction MOSFET makes designs easy.
