Shenzhen Mingjiaoda Electronics Co., Ltd. [Supply] Power Integrations LNK6404D: energy-efficient, accurate primary side regulation CV/CC switches for adapters and chargers, quality assurance, original genuine, the actual order can be discussed in detail!
Introduction: LNK6404D LinkSwitch™-3 Series
The LinkSwitch™-3 series of integrated circuits greatly simplifies the design of low-power CV/ CC chargers by eliminating the need for an optocoupler and secondary control circuit. The devices introduce a revolutionary control technique that provides very precise output voltage and current regulation, compensating for transformer and internal parameter tolerances as well as input voltage variations.
The device integrates a 725 V power MOSFET, a novel on/off control state machine, a high voltage switched current source for self-biasing, frequency jittering, cycle-by-cycle current limiting, and hysteretic thermal shutdown circuitry on a monolithic IC.
Product Highlights
Dramatically simplifies CV/CC converters
- Eliminates optocouplers and all secondary CV/CC control circuits
- Eliminates all control loop compensation circuitry
Advanced Performance Features
- Compensates for transformer inductance tolerances
- Compensates for input line voltage variations
- Compensates for cable voltage drop
- Compensates for external component temperature variations
- Very accurate IC parameter tolerances using test trimming techniques
- Frequency dithering significantly reduces EMI filter costs
- Programmable switching frequency up to 85 kHz to reduce transformer size
- Fixed minimum operating frequency for improved transient load response
Advanced Protection/Safety Features
- Automatic restart protection reduces power in the event of output short circuits and control loop failures (component opens and shorts) by more than 90%.
- Hysteretic thermal shutdown - automatic recovery reduces power return from the field
- Meets high voltage creepage requirements between DRAIN and all other pins on PCB and package
Applications
- Chargers for mobile/cordless phones, PDAs, MP3/portable audio devices, adapters, etc.
