SY8003 instead of SY8003A

[someonenotyou]

Hi.

I have a Lenovo HLS1C_HLS1D LA-L502P board with bad SY8003A DC/DC converter.
I have a different mother board witch contains SY8003 DC/DC converter.

Can I use SY8003 instead of SY8003A converter?

These are the differences -

• Short Circuit Protection:
  • SY8003: Uses latch-off protection. This means that when a short circuit is detected, the device will shut down and remain off until it is manually reset.
  • SY8003A: Uses hiccup mode protection. In this mode, the device will repeatedly attempt to restart after a short circuit is detected. If the short circuit persists, it will continue to cycle on and off until the fault is cleared.
• Over-Voltage Protection:
  • SY8003: Has latch-off protection for over-voltage conditions. Similar to short circuit protection, the device will shut down and remain off until manually reset.
  • SY8003A: Does not have latch-off protection for over-voltage conditions. It will continue to operate without shutting down.

Thank you.

Based on the shared differences, yes. Keep in mind that if there was a trigger even like over-voltage, this regulator will shut off and only a power cycle of the board will reset the device.
