LNK623

LNK623-626 LinkSwitch-CV Family Energy-Efficient, Off-line Switcher with Accurate Primary-side Constant-Voltage (CV) Control Product Highlights Dramatically Simplifies CV Converters Eliminates optocoupler and all secondary CV control circuitry Eliminates bias winding supply – IC is self biasing Advanced Performance Features Compensates for external component temperature variations Very tight IC parameter tolerances using proprietary trimming technology Continuous and/or discontinuous mode operation for design flexibility Frequency jittering greatly reduces EMI filter cost Even tighter output tolerances achievable with external resistor selection/trimming Advanced Protection/Safety Features Auto-restart protection reduces delivered power by >95% for output short-circuit and all control loop faults (open and shorted components) Hysteretic thermal shutdown – automatic recovery reduces power supply returns from the field Meets HV creep...
