ICC80QSG Overview
The ICC80QSG is a voltage mode controller for flyback topologies operating in quasi-resonant mode and valley switching DCM, to achieve high efficiency of power transfer across wide operating range. For battery charging application, the IC offers a wide power range as well as a prehensive set of protections. The IC is easy to design in and requires a minimum number of external ponents.
ICC80QSG Key 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
- 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
- Adjustable maximum on-time
- limits input power and current allowing safe-operation under low line
- prehensive set of protections
- internal overtemperature protection (OTP)
ICC80QSG 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
