LNK626PG Pinout Equivalent

LNK626PG, as a highly integrated off-line switching power supply controller with a switching frequency of 100khz, adopts quasi-resonant flyback topology design, and can stably output 8.5W power under a wide voltage input of 85-265VAC. Its unique valley bottom switching technology effectively reduces switching loss, and the conversion efficiency in applications reaches up to 88%. Chip also built-in multiple protection mechanism (overtemperature 145℃ off/overvoltage 32V lock), with dynamic base drive technology, very suitable for small home appliance control circuit board, LED drive circuit, etc., in the PCB layout is best to reserve RCD absorption circuit adjustment space to be compatible with different alternatives.

Pins are defined as follows:

In the device selection of isolated AC-DC power circuit, due to the differences in internal architecture, protection mechanism and control logic of chips from different manufacturers, there are compatibility risks in most cases of direct replacement. For the replacement needs of isolated AC-DC power ics, we generally choose the following two solutions:

1 Original factory iteration plan: preferentially use the same brand and series upgrade/downgrade models (upgrade models can achieve perfect compatibility)

2 Third-party compatibility scheme: Select pin-compatible chips produced by reverse engineering or licensing (note subtle differences in functional parameters)
