buck LED driverconstant currentintegrated 90 V MOSFET140 kHz PWMESOP-8half-brightness control

OC5738 is a 140 kHz buck LED constant-current driver with an integrated 90 V MOSFET for 8 V to 90 V LED lighting systems.

Best for

  • High-power buck LED drivers
  • Electric bicycle and motorcycle lamps
  • Automotive lighting circuits within the stated voltage limits
  • LED backlight power stages

Avoid if

  • Applications requiring documented RoHS, REACH, MSL, or lifecycle status
  • Designs requiring LED current above 1.2 A
  • Input voltages outside 8 V to 90 V

Check before use

  • Set RCS according to ILED = 0.2 / RCS
  • Keep current-sense and GND traces short and low resistance
  • Place the input capacitor close to VDD and GND
  • Confirm thermal performance at the required LED current
