Maker : O2Micro International

Pinouts :
OZ9956B datasheet

Description :

OZ521 ~ OZ9998H Information

OZ9956B is a high efficiency, DC/DC controller that drives up to six (6) strings of LEDs in parallel configuration, with multiple LEDs in each string connected in series. It is targeted for notebook/netbook applications.

It provides six (6) LED current sense inputs in an “OR” configuration for improved backlight reliability. This allows the backlight to remain functional in the event that any string (s) is damaged during normal operation.

OZ9956B can receive either an analog signal or an external Pulse Width Modulation (PWM) signal for the dimming control function. This IC provides an integrated circuit to balance the current flow through each LED string, as well as, the integrated power MOSFET.
