AI summary

OC5128 product

OC5128 is a 100 V internal-MOSFET buck LED driver for constant-current outputs from 100 mA to 1.8 A.

Best for

High-power LED constant-current drive
Automotive and electric-bicycle lighting
DC or AC-input LED applications

Avoid if

A verified lifecycle or compliance declaration is mandatory but unavailable
The design requires a package other than ESOP8

Check before use

Confirm the LED current using RCS
Confirm the inductor meets the continuous-mode minimum
Check thermal dissipation and the 0.8 W ESOP8 package limit
Verify MODE wiring for full or half brightness
