RT8463
Overview
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.
- High Voltage : VIN Up to 50V, VOUT 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
