Datasheet for ICC80QSG
Features
The ICC80QSG flyback controller is tailored for battery charger application to meet the required performance. Features
- Secondary side regulation (SSR), for battery charging current control
- High efficiency and low electromagnetic interference (EMI) with quasi-resonant valley switching
- Quasi-resonant mode (QRM) operation with continuous conduction mode (CCM)-prevention and valley switching discontinuous conduction mode (DCM) in mid to light load
- Burst mode for very light loads and low system standby power consumption
- Reduced gate driver output voltage during burst mode for lower standby power
- Adjustable on-time mapping at valley changing position, for the desired maximum operating switching frequency
- Adjustable maximum on-time
- limits input power and current allowing safe-operation under low line condition
- prehensive set of protections:
- internal overtemperature protection (OTP)
- flyback output overvoltage protection (OVP)
- primary side over-current protection (OCP)
- brownin protection
- brownout protection
- VCC overvoltage protection
- open loop protection
- input overvoltage protection
- Externally configurable hysteresis of brownin and brownout
- Adaptive brownout level triggering based on bus voltage ripple
- protect primary ponents from overheating and saturation with higher brownout level at higher input/output power
- Supports on/off control with external pull-down signal
- Soft start to reduce ponent stress during turn-on
- External start-up circuit control signal
Potential applications
- Tailored for battery charger application up to 130 W
- Also suited for adapter, printer, PC, TV, monitor, set-top box, audio amplifier applications up to 130 W
