Summary:
CX7560 is a high-performance, multi mode PWM control chip. The chip can work in frequency hopping and green modes to reduce losses during no-load and light load, as well as QR and CCM modes to improve the overall efficiency of the machine.
CX7560 only requires a small amount of current during startup and operation, and a large resistor can be used in the startup circuit to further reduce power consumption during standby.
CX7560 has multiple built-in protections, including: input voltage low protection (Brown out), input voltage high protection (Line ovp), output voltage overvoltage protection (VO-OVP), output diode short circuit protection, cycle by cycle overcurrent protection (OCP), overload protection (OLP), VDD overvoltage protection (OVP), VDD undervoltage protection (UVLO), over temperature protection (OTP), etc.
CX7560 is packaged in SOT23-6.
Characteristic:
Standby power consumption below 75mW within the full voltage range
Multiple working modes: CCM @ heavy load, QR @ medium load
Green Mode @ light load, Burst Mode @ empty load
Noisy operation
Built-in frequency jitter function to improve EMI performance
Built-in soft start function to reduce power tube stress
