Infineon has launched a brand new single-stage flyback controller for secure and sturdy AC-DC battery charger designs for a lot of purposes.
Battery-powered home equipment, one of many trade’s fastest-growing segments, require energy-efficient, sturdy, and cost-effective battery charging. Battery charger ICs are built-in circuits (IC) which can be used to cost batteries. There are a number of varieties of battery charger ICs. Linear chargers use a voltage-controlled supply to drive a set voltage to seem on the output terminal.
Infineon Applied sciences has launched the ICC80QSG, an AC-DC controller ICs introducing single-stage PWM controller for flyback topologies. The ICC80QSG battery charging IC presents a quasi-resonant mode, switching in valley n (QRMn). Its QRM operation comes with steady conduction mode (CCM) prevention and valley switching discontinuous conduction mode (DCM) in mid to mild load.
By pairing ICC80QSG with CoolMOS™ P7 MOSFET units, excessive effectivity and low electromagnetic interference (EMI) might be achieved to allow financial savings on the general BOM: fewer heatsinks and coils could also be wanted in flyback designs. As well as, the built-in burst mode operate for very mild hundreds permits designs with very low energy consumption throughout standby mode.
Moreover, the ICC80QSG encompasses a decreased gate driver output voltage throughout burst mode, making it ideally suited to very low standby necessities beneath mild load or no load situations with a outstanding standby efficiency over the entire working vary.
The ICC80QSG implements a secondary-side regulation (SSR) technique, which is right for present management throughout battery charging. For increased design flexibility, it accommodates adjustable on-time mapping on the valley altering place for the specified most working switching frequency, in addition to adjustable most on-time that limits enter energy and present, permitting secure operation beneath low line situations.
The IC options an externally configurable hysteresis of brown-in and brown-out to guard the first MOSFET by guaranteeing it doesn’t get overheated even with fewer heatsinks throughout enter undervoltage with tight brown-in/brown-out hysteresis. Along with a complete set of safety options, the IC helps understand straightforward, secure and sturdy AC-DC battery charger designs for a lot of purposes.
