OB2269AP Current Mode PWM Controller IC - DIP-8 Package
type: Product
description: OB2269AP Current Mode PWM Controller IC - DIP-8 Package is a highly integrated current-mode PWM controller designed for offline AC/DC flyback power supplies. It provides programmable switching frequency, burst-mode operation for improved light-load efficiency, internal slope compensation, leading-edge current-sense blanking, and comprehensive protection functions. The IC is suitable for SMPS applications such as power adapters, battery chargers, set-top boxes, televisions, and other compact AC/DC power supplies. Features: Current-mode PWM control. Designed for offline AC/DC flyback converters. Externally programmable PWM switching frequency. Extended burst-mode operation for reduced standby power. Low startup current. Internal synchronized slope compensation. Leading-edge blanking on the current-sense input. Cycle-by-cycle over-current protection. Overload and over-temperature protection. VDD over-voltage protection and under-voltage lockout. Gate-drive output voltage clamped to protect the external MOSFET. Frequency-shuffling technology for improved EMI performance. DIP-8 through-hole package.
