Part Number : DDA010, ( = ICE2QR0665 )
Function : Off-Line SMPS Quasi-Resonant PWM Controller
Package : DIP 8 Pin Type
Manufactures : Infineon
The DDA010 is Off-Line SMPS Quasi-Resonant PWM Controller with integrated 650V.
The CoolSET-Q1 series (ICE2QRxx65) is the first generation of quasi-resonant integarted power ICs. It is
optimized for off-line switch mode power supply applications such as LCD monitor, DVD R/W, DVD
Combo, Blue-ray DVD, set top box, etc. Operting the MOSFET switch in quasi-resonant mode, lower EMI, higher efficiency and lower voltage stress on secondary diodes are expected for the SMPS. Based on the BiCMOS technology, the CoolSET-Q1 series has a wide operation range (up to 25V) of IC power supply and lower power consumption.
1. 650V avalanche rugged CoolMOS with built-in startup cell
2. Quasiresonant operation till very low load
3. Active burst mode operation for low standby input power (< 0.1W)
4. Digital frequency reduction with decreasing load for reduced switching loss
5. Built-in digital soft-start
6. Foldback point correction and cycle-by-cycle peak current limitation
