LC5513D description the lc5500 series is a quasi-resonant topology switching power supply ic, designed for input capacitorless applica- tions, and making it possible for systems to comply with the harmonics standard (iec61000-3-2 class c). it incorporates separate controller and power mosfet chips. the control- ler adapts the average current control method for realizing high power factors, and the quasi-resonant topology contrib- utes to high efficiency and low emi noise. the rich set of protection features helps to realize low component counts, and high performance-to-cost power supply. the LC5513D is intended for non-isolated designs. the incorporated mosfet has a v dss (min) rating of 650 v and r ds(on) (max) of 1.9 . it is capable of a maximum output power of 20 w on 230 vac supply and 16 w on universal supply based on the thermal rating. note that the maximum output power can be up to 120% to 140% of this value. however, it may be limited in applications with low output voltage or short duty cycle. features and benefits ? integrated on-width control circuit (it realizes high power factor by average current control) ? integrated startup circuit (no external startup circuit necessary) ? integrated soft-start circuit (reduces power stress during start-up on the incorporated power mosfet and output diode) ? integrated bias assist circuit (improves the startup performance, suppresses v cc voltage droop during operation, allows reduction of vcc capacitor value as well as use of a ceramic capacitor) ? integrated leading edge blanking (leb) circuit ? integrated maximum on-time limit circuit ? dual-chip structure, with an avalanche-guaranteed power mosfet (allows simplified surge suppressing circuits) ? protection features: ? overcurrent protection (ocp): pulse-by-pulse ? overvoltage protection (ovp): pins vcc, isense, and ocp, intermittent oscillation operation ? overload protection (olp): intermittent oscillation operation ? thermal shutdown (tsd): halts switching operation and latches in the off-state single-stage power factor corrected off-line switching regulator ic typical application package: 8-pin dip not to scale vcc s/gnd isense comp controller chip d/ st LC5513D 1 3 6 4 2 8 ocp v in (a c ) led 48102.007
