LNK616GG - Brand New Power Integrations AC DC Converters, Offline Switchers
-
Description
The LNK616GG is a member of the LinkSwitch™-3 family of ICs, designed to simplify low power CV/CC charger designs by eliminating the need for an optocoupler and secondary control circuitry. It introduces a revolutionary control technique that provides accurate output voltage and current regulation, compensating for transformer and internal parameter tolerances, as well as input voltage variations.
Specifications and features
- Dramatically simplifies CV/CC Converters
- Eliminates optocoupler and all secondary CV/CC control circuitry
- Eliminates all control loop compensation circuitry
- 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 technology
- Frequency jittering greatly reduces EMI filter cost
- Programmable switching frequency up to 85 kHz to reduce transformer size
- Minimum operation frequency fixed to improve transient load response
- Auto-restart protection reduces power delivered by >90% for output short-circuit and control loop faults (open and shorted components)
- Hysteretic thermal shutdown – automatic recovery reduces power supply returns from the field
- Meets high-voltage creepage requirements between DRAIN and all other pins both on the PCB and at the package
- Easily meets all global energy efficiency regulations with no added components
- No-load consumption at 230 VAC input with bias winding <10 mW for LNK64x4-LNK64x6 and <30 mW for LNK64x7-LNK64x8
- ON/OFF control provides constant efficiency down to very light loads – ideal for CEC regulations
- No current sense resistors – maximizes efficiency
- Halogen free and RoHS compliant package
Application Scenarios
- Chargers for cell/cordless phones, PDAs, MP3/portable audio devices, adapters, etc.
