BF1510 Datasheet | BYD Microelectronics

BYD Microelectronics Co., Ltd. Offline AC/DC Switcher IC General Description BF1510 is a highly integrated summing mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback converter applications in sub 30W range. The PWM switch frequency is created by a VCO (voltage control oscillator) which consisted in BF1510. Simultaneously, the frequency is externally programmable and trimmed to tight range. In a typical condition (RI=100K), the switch frequency is 65 KHz. At no load or light load condition, the IC operates in extended “burst mode” to minimize switching loss, lower standby power and higher conversion efficiency is thus achieved. BF1510 offers plete protection coverage with auto self-recovery including cycle-by-cycle current limiting, over load protection and SENSE pin short protection, etc. The gate driver is clamped to maximum about 12V to protect the power MOSFET.
