EUP9268 ds9268 ver1.0 nov. 2015 1 constant-voltage constant-current flyback controller using opto-coupled feedback description the EUP9268 is a high performance ac-dc power supply controller which provides constant output voltage (cv) using the secondary side regulation (ssr) and accomplishes constant output current (cc) through primary-side regulation (psr) techniques. the device together with an external depletion mode nfet provides a fast start-up time without consumin g extra power dissipation in no-load. the drive outpu t interfaces to a mosfet power switch. discontinuous conduction mode (dcm) with valley-switching effectively reduces switching losses. the controller operates in pulse width modulation mode (pwm) or pulse frequency modulation mode (pfm) automatically to keep the conversion high efficiency within the line ranges and contains ther mal shutdown function, over-voltage protection and over-current protection. a wide switching frequency range from 170hz to 100khz can achieve both less than 30mw no-load power dissipation and high average active efficiency. typical application circuit features <30mw no-load power. 1% voltage regulation and 5% current regulation clamped gate-driver output for mosfet 170hz ~ 100khz switching frequency tiny external components opto-coupler feedback of cv and primary side regulation(psr) for cc active start-up scheme enables fastest possible start-up. available in sot23-6 and sop-8 packages rohs compliant and 100% lead (pb)-free halogen-free applications adapters for consumer electronics ac/dc power figure 1. sot23-6 typical application circuit
