RT8532GQW規(guī)格書詳情
Description
The RT8532 is a high efficiency white LED driver. It is
designed for LCD panel that employs a LED array as the
lighting source. An integrated switch current mode Boost
controller drives six strings in parallel and supports up to
10 pieces of LEDs per string. The internal current sinks
support maximum ±2 current matching for excellent
brightness uniformity in each LED string. To provide enough
headroom for the operating of current sink, the Boost
controller monitors the minimum voltage of feedback pins
and regulates an optimized output voltage for power
efficiency.
The RT8532 has wide input voltage range from 2.5V to
24V and provides adjustable 5mA to 50mA LED current.
The internal 200mΩ, 43V power switch with current-mode
control provides cycle-by-cycle over current protection.
The RT8532 also integrates PWM and analog dimming
functions for accurate LED current control. The input PWM
dimming frequency can be operated operate from 100Hz
to 20kHz without any inrush current in LED.
The RT8532 is available in WQFN-20L 3x3 package.
