Component

100 V MOSFETbuck LED driverconstant currentPWM dimminganalog dimmingESOP-8

OC5020B is an integrated 100 V buck LED driver for constant-current lighting designs using fixed-off-time peak-current control.

Best for

  • Buck LED drivers below the 100 V switch rating
  • Compact high-power LED lighting
  • PWM or analog dimming applications

Avoid if

  • Compliance or lifecycle status must be confirmed
  • The design requires a documented automotive qualification
  • The required switch-node voltage can approach or exceed 100 V

Check before use

  • Confirm actual input and transient voltage margin
  • Set RCS, COFF, and L1 for the required LED current
  • Keep CS and GND sensing traces short and low resistance
