RT8463GQW IC LED DRVR RGLTR PWM 2A 12WDFN
LED Driver IC 1 Output DC DC Regulator Step-Down (Buck), Step-Up (Boost) Analog,
PWM Dimming 2A (Switch) 12-WDFN (3x3)
Description
The RT8463 is a current mode PWM regulator for LED driving applications. With a 2A power switch, wide input
voltage (4.5V to 50V) and output voltage (up to 50V) ranges, the RT8463 can operate in any of the three
common topologies : Buck, Boost or Buck-Boost. With 470kHz operating frequency, the size of the external
PWM inductor and input/output capacitors can be minimized. High eficiency is achieved by a 100mV current
sensing control. Brightness dimming can be controlled from either analog or PWM signal. A unique builtin
clamping comparator and filtering resistor alow easy low noise analog dimming
conversion from PWM signal with only one external capacitor.
The RT8463 is available in the TSSOP-14 (Exposed pad)
and WDFN-12L 3x3 packages.
Features
●High Voltage : VIN Up to 50V, Vour Up to 50V
●Buck, Boost or Buck-Boost Operation
●Built-In 2A Power Switch
●Current Mode PWM Control
●470kHz Fixed Switching Frequency
●Easy Dimming : Analog, PWM Digital or PWM Converting to Analog
with One External Capacitor
●Adjustable Soft- Start to Avoid Inrush Current
●Adjustable Over Voltage Protection to Limit Output Voltage
●Thermal Shutdown
● Under Voltage Lockout
●RoHS Compliant and Halogen Free
Applications
●GPS, Portable DVD Backlight
●Desk Lights and Room Lighting
●Industrial Display Backlight
