OZ9984

FEATURES

• Drives up to 4 LED strings in parallel

• Integrated LED current balance control circuit

• Multi-chip parallel operation

• Analog dimming control

• Over-voltage protection (OVP)

• User-defined LED short circuit protection

• Soft start function

GENERAL DESCRIPTION

OZ9984 is a high efficiency LED driver IC that works in conjunction with a pri-

mary side external Pulse Width Modulation (PWM) controller for offline, isolated

LED lighting application. It has four (4) LED current sense inputs in an “OR”

configuration to ensure uniform lighting of the LEDs. It can drive up to 4 strings

of LEDs in parallel and up to 9 LEDs per string connected in series.

OZ9984 supports up to 350mA of LED current per string. It is designed in such

a way that if any LED string is damaged during normal operation, the remaining

string (s) continue normal operation. Multi-chip parallel operation supports ad-

ditional LED strings.
