OB2269 OB2269CP Shanghai Guoxin GC2269 SOP-8 Power Management IC Onbo OB2269CCPA

GC2269 is a PWM control circuit integrated chip, it has a low standby power consumption, low cost and other characteristics, can be used in off-line flyback converter applications, in no-load or light-load conditions, the IC operates in the “intermittent mode” to reduce the loss of the application system, can realize the function of low standby power consumption and high conversion efficiency.

The VDD has low start-up current and low operating current, which contributes to the reliability of the GC2269 start-up design, and a large resistor can be designed in the application circuit to divide the voltage to start the chip operation. The GC2269 is also designed with an internal slope compensation function, which improves the stability of large signals in the system.The GC2269 is also designed with internal protection modules that provide protection, including over-current protection (OCP), overload protection (OLP), over-voltage protection (OVP), over-temperature protection (OTP), under-voltage lockout (UVLO), etc. The gate drive output voltage can be up to 10V. The gate drive output voltage is up to 18V, which serves to protect the MOSFET. In addition GC2269 has excellent EM performance.
