Description :

The CR6842 is a low startup current , low cost, current mode PWM controller with Green-Power & burst-mode power-saving operation. The integrated functions such as the leading-edge blanking of the current sensing, internal slope compensation provide the users a high efficiency, low external component counts, and low cost solution for AC/DC power applications.

Features :

1. Low Cost, Green-Power Burst-Mode PWM

2. Very Low Start-up Current ( about 7.5µA)

3. Low Operating Current ( about 3.0mA)

4. Current Mode Operation

5. Under Voltage Lockout (UVLO)

6. VDD Over Voltage Protection(OVP)

7. programmable over-temperature protection

8. Internal Latch Circuit(OTP,OVP)

9. Built-in soft start with 1ms

10. Built-in Frequency jitter for better EMI Signature

11. Soft Clamped gate output voltage 16.5V

Applications :

1. Power Adaptor

2. Battery Charger Adapter

3. Open Frame Switching Power Supply
