POWER INTEGRATIONS LNK4013D-TL Datasheet & Stock

LinkSwitch™-4 family energy-efficient, accurate primary-side regulated CV/CC switcher for adapters and chargers of ICs dramatically simplifies low power CV/CC charger design by eliminating an optocoupler and secondary control circuitry. The LinkSwitch-4 family adaptive BJT drive technology uses combined base and emitter switching to boost switching performance and deliver higher efficiency, wider reverse bias safe operating area (RBSOA) margin and the flexibility to accommodate a wide range of low cost BJT. The device incorporates a multimode PWM/PFM controller with quasi resonant switch to maximize the efficiency, meets low no-load power and at same time maintain fast transient response greater than 4.3V with a load change from 0% to 100%. Very accurate IC parameter tolerances using proprietary trimming technology. Applications includes chargers for cell/cordless phones, PDAs, MP3/portable audio devices, adapters, networking, etc.
