G5356 Global Mixed-mode Technology Wide AC Input Range Controller IC for Offline LED Lamps Features General Description The G5356 is an LED driver for AC line input lamps. It features a simple solution with non-isolated buck topology for off-line lighting applications. The device uses fixed off-time and average current sensing voltage to reduce the amount of external components. Additional features include thermal shutdown and input supply under-voltage lockout. Simple solution for offline lighting applications Application voltage range 80VAC – 277VAC Low quiescent current Programmable off-time allows for constant ripple current Input supply under-voltage lockout Thermal shutdown No visible flicker SOP-8 package Applications Retro Fit Lamps Solid State Lighting LED modules such as LED spots, down-lights LED strings suitable for retail displays, etc. Ordering Information ORDER NUMBER MARKING TEMP.
